Going a little off topic, I think this could generate some legitimate discussion.
Wouldn't game planning and adjustments be a worth while tool to use when evaluating a player in the preseason? IMO, it would. Right now, they pretty much just go out there and run plays, and evaluate how the player does. But during the regular season, that's not what happens at all.
Wouldn't it be favorable to a coaching staff to design gameplans and configure adjustments in the preseason to watch how well the player can carry out those orders? Can they stick with their assignments? Do they freelance? Do they have the mental makeup to be able to not just act on talent alone, and instead be able to read-and-react while simultaneously processing their assignment(s)?
I think that would be a very important factor, especially for the Bills, who claim to value how smart they want their players to be. On the other hand, if this was actually an effective method, I'd think coaches around the league would actually be doing it.
