Well I agree he has made the team better. Replacing Ochebo, Randall, and Haughton with successful, experienced players from mid level programs is a definite improvement. The 2G replacement is also an improvement, so with those additions plus our returning three starters, Nix (possibly), Jones Jeter, and a few of our other returning subs, the reality is of course we're better.
IMO however, those additions were not the original recruiting plan. Jamie missed on at least three transfers (maybe a few more) and also on some h.s grads. This was a "stop-gap" approach at best, and these guys were not Jamie's first choices. As for not wanting to go "younger," I don't agree. If he were able to get his first line choices, IMO he would have gladly gone younger.
As for this coming season, I feel he did the best he could and as I previously said, we are definitely improved from last year. I'm hoping he can make these different pieces work. This team still has defensive deficiencies, and big question marks with the additions, but I do see major improvement. It is also crucial that he gets back to decent recruiting and player development that fits his system.
