Neither Sark nor Wilcox preached discipline. Wilcox had very good talent to work with and IMO coached them more to create the big play than he did basic fundamentals, critical to players not long removed from High school. This tackling the ball stuff is great when it works, but I've seen enough missed tackles to understand a certain stop outweighs a potential strip. The initial defender has to go for the stop, if he can hold the carrier up, while holding him back, then someone else can step in and go for the strip. Too often this year we watched RBs run past the tackler as the tackler focused entirely on the ball. It's not the way the game should be played, IMO.
Having your views challenged is a lot more healthy than simply jabbering on with people who think exactly the same way as you.
