I find it quite strange that given how commercialised American Sports are, their jerseys/uniforms are seen as sacred, they generally keep the one design and never change. You'd think they'd be slapping sponsors on there and milking as much money as possible out of the fans. Football clubs around Europe/South America are pretty much seen as religions whereas I think we view the "franchises"(horrible word) in the US as quite fairweather, I mean it's pretty much unheard of for a football team to just up and leave - only Wimbledon/MK Dons springs to mind in recent history but it happens frequently in the US.
In America, especially in professional sports (and REALLY in football and basketball), logos and uniforms are "sacred" so to speak. There are a couple professional franchises that are adopting the use as many bright colors and combinations as possible but only a handful (Seattle Seahawks,and Jacksonville Jaguars are really the only two NFL teams and the Charlotte Bobcats (now the Hornets again so that will stop and maybe the New Orleans Pelicans (formerly the Hornets...long story if you don't know it) in the NBA). You'll notice that very few NFL logos have actually changed the last 75 years. There have been some "modernizing" of some and cleaning some lines up but not a lot of complete re-branding. Teams that do re brand and change logos/color schemes go through years of public input and research.
There are infinite ways for American sports franchises to make more money than they know what to do with rather than changing logos, colors, and sponsors every year and forcing people to buy new uniforms. They know American's won't buy them new every year - a new football jersey costs roughly $175 (or roughly £105). American's see that for what it is and won't do it. There are many, like me, who have worn the same shirt/jersey to games (on game days) for years with no intention of changing it.
The NFL has experimented with putting sponsor logos on practice jerseys and there was rather large backlash to that. It was/is a 3x5 logo on the left shoulder and there is backlash over over commercializing the teams. There was brief...very very brief...discussions about doing that on game jerseys and that was met with 100% negative...extremely negative...reviews and was squashed within 2 days of it being floated.
The NBA has floated the idea of going the route of sponsorships on jerseys and that was met with the same anger as the football uniforms. You'll notice that about 75% of the league is wearing the same jersey style that they were in the 70s. They've all run "alternates" out occasionally but those have been hated with a passion 98% of the time.
The WNBA does it. They didn't at first but were running bankrupt. They then went full soccer kit with it and found that it recieved negative feedback from those that actually watch the WNBA (about .005% of Americans) and went to something like this...It works int he WNBA but you'll NEVER see the NBA wear it
We don't want logos on our jerseys. Now, we have no problem going to see our team play on *Field Sponsor*nat *Stadium Sponsor* Stadium where the concourses, bathroom walls, beer cups, food wrappers, game program, scoreboards, etc... are littered with sponsorships with each time out being sponsored by some corporate sponsorship and almost each action (depending on the sport) being sponsored by someone. Keep it off of our uniforms, t-shirts, and hats and we're fine. There is a growing number of fans getting sick of EVERYTHING being sponsored but when given a choice of that or sponsors on the uniforms they quickly quiet down.
As for the teams up and moving and being fairweather fans. That has nothing to do with the fans - except in the case of the potential Jacksonville Jaguars move. That was a mistake from that start - why the NFL put a third NFL team in a state that is notirous for not supporting their professional sports (I'll grant you Florida doesn't support their teams) where the teams that were already there had been there for decades and expect to carve a fan base out of it I'll never understand.
Almost every single time a team has moved it has been because the owner had issues with money. There is a lot of talk of "I'll move the team" but it's always to drum up money for a new stadium/arena and rarely ever happens in all reality. You name me a team that moved in the last 30 years and I'll show you an owner that got in a dispute with the city over money. It used to happen a lot more in the 40s, 50s, 60s, 70s, and 80s before professional sports are what they are today. That was when professional athletes were still working jobs during the off season because sports were just a "professional hobby".
It has nothing to do with fair-weather fans. Many times the fans are left wondering "What the f***" and are ****ed about it. When the Cleveland Browns were moved to Baltimore in 1996 by the owner Cleveland fans were absolutely livid and still went to the stadium every Sunday to tailgate before getting a team back. When that owner died a year, or so ago, they celebrated (he was one of the most influential owners NFL history and is why the NFL is what it is today). NBA or MLB fans of newer, transplanted, teams may be fair-weather but NFL fans are anything but. There is a reason the average NFL team is worth about 1.3 billion dollars while almost all being less than 60 years old. As proof of the worth of the NFL they settled a concussion lawsuit last fall for $765 million and it is considered pocket change for the league. One expert I read said it was like losing about $50 to the average American (or £30 to the average Brit).
Part of the fair-weather that some Americans may have comes from the number of different leagues we have (pardon my ignorance of professional leagues in England). There is the NFL, NBA, NHL, and MLS...couple that with countless "lower level" football, basketball, and hockey leagues. Couple that with the fact that there are 336 universities in America that play Division 1 (the highest level) basketball and 246 universities that play Division 1 football. There are professional sports on television 361ish nights per year.
There are over 1,000 colleges and universities that play basketball and football in America
I can tell you I am as dedicated to the teams that I follow as the vast majority of you are to Tottenham - the problem is trying to split that dedication between 3 college football teams, an NFL team, a NBA team, a NHL team, and a MLS team and 3 college basketball teams takes quite a lot. To go on top of that I watch darts, rugby, cricket, anything any time it's on TV. The reality is most Americans are "burnt out" on sports.
With all that said NFL teams averaged something like 65K per game this season (Every team) with the majority likely able to sell out stadiums of 80-90k if they were built that big. There are about 10 university teams in America that average over 100k per home game. My favorite of them, the University of Michigan, averages about 114k people per game. With the access that 80inch HD TVs, massaging recliners, surround sound, etc... has given people at home to watch a game with a much better view of the game, at a much lower price, than being at the game.
Being honest - wouldn't you love to have a jersey that doesn't have the logo as a small patch, almost afterthought like, hidden on the shoulder with some big corporate sponsor taking up 2/3 of the front? To have Tottenham or Spurs across the chest so it feels like the player is representing the club and not AIA, HP, Fly Emirates, etc..?
Sorry, from now on I'll try to only contribute in regards to Tottenham kits unless this subject continues.
