But what's the value of those other stats to evaluate a DM? Particularly when compared to other aspects such as positioning, discipline, concentration, consistency, things that are hard to measure using stats.
Then there's the point that there are a lot of other stats available to those that want to pay for them. I agree, we don't get the raw data, but that doesn't mean what we do get is completely meaningless.
And, again, a higher number does not necessarily mean better. One of our very best players in recent decades in that position was Carrick, not exactly an all action ball winning DM.
To me the comparison with Ward Prowse should end with the conclusion that Ward Prowse is also quite good at some of these things. Good for him, good for Southampton. Tells us little to nothing about Hojbjerg who as far as I can tell has good defensive stats.
Or do you have some kind of threshold in mind that Hojbjerg should have reached on these stats to be "good enough"?
