But both left clubs known for their "model"
Everyone wants to step up to the big seat, but sometimes you have to know where you're at your best.
And Spurs, with all their injuries this season and terrible finish last season, was always going to be a tough test to make successful this season, for any manager
I think it's both a bit simpler, and more revolutionary than that. It's becoming more like American sports, where the "head coach" is important, but if he doesn't control player acquisition, he's deemed more expendable.
For instance, if we believe Moyes is at the top of the player acquisition model, and coaches the squad, then he becomes more difficult to replace and therefore more difficult to sack.
The opposite is true, if you're someone like Potter who is coaching the squad but others are "buying the groceries,", it becomes much easier to sack you as it won't impact the other football operations.
I mean, what will change at Brighton if they sack Huerzler? Not much.
That, along with all of the substitutions able to be made now, are creating situations where I think you'll see much more specialization (set pieces, throw ins etc, players who become starters and finishers etc). It's inevitable, but I think to the detriment of the game.
