I don't know if it would have meant fewer injuries or more. I didn't think the Bobcats were aggressive enough, and that didn't help them stay in the game. From his post-game comments, I think Solich agreed, and the week between Louisvile and NTSU I know he scheduled extra hitting in practice.
It's always going to be a fine line - too much hitting and you have too much risk of injury, whereas too little hitting, and the players aren't aggressive enough, and not used to getting hit. There's no magic answer, and what's the right answer for one group of players isn't going to be the answer for the next group. That's where you have to rely on the Coach's intuition. He's the one that sees the players in practice, day in, and day out, so he's the one in the best position to guess just how much hitting they need or don't need. Every Coach will misjudge it a bit, from time to time, but a good Coach will realize quickly and fix the problem, whereas some other Coach might just keep up what he was doing and trying to apply the same answer for all players.
L.C. - Yet again, breaking it down beautifully. There is a fine line when it comes to practice intensity and only the coach has a good grasp on the situation. Taking a quote straight from Frank, "Play on the Edge", you have to know how far to push the boys. Each team (players for that matter) has different limits from year to year. Take a 10year vet in the NFL... He may not need all of the OTAs or preseason games to get ready for the season & still come out and play at a high level. Others, especially younger players, benefit greatly from the intensity of practice and getting used to game speed.
Bottom line, it is up to the coach to read the team and make changes to the schedule accordingly.
