If I were one of these players I might be a little upset that I can't go out there to warm up on game day, but at the same time I would understand that there is no use. Like gamecocks said. I am sure the parents are pissed off, because well, many times parents and sports don't get along together.
I heard Davidson say that the players weren't really into it on the sidelines too. At the same time I don't ever remember someone saying that the players were really into it, ever.
I don't think warming up is the problem. Who knows what the problem is or if there even is a problem.
I think the same thing goes for in practice, they just stand their and don't do much. To them it seems like a waste of time. Having bad team chemistry and kids upset isn't a good thing.
You think? Do you know? What would be the point in having a scout team if they don't do anything? Callahan is one for trimming fat, evident in the cutting down of the walk on program, so I don't think he would have a whole squad of kids put the pads on every day just to sit there.
It comes down to roles for me. You have to know your role on the team. If you don't like your role, work to change it or don't be a part of the team. I have been on teams in various sports over the years and have had at least a couple different roles. At least one of which was more of a support role. Did I complain that I didn't get to get out on the field every game? No because I understood my role. Would I have taken the opportunity to get out on the field? HELL YES.
This is college football, not a little league where one of the rules is that everyone plays and feels warm and fuzzy inside.
