If you do leave, wish you lots of success, and I have enjoyed competing against you. You were at Columbia when I was at Fordham in Phelan, back when we had the Ivy league full and it became pretty powerful. One of the things I enjoyed most about that conference was that we all set up a thread on the Ivy League forum, and we would all write about our teams, focusing on what players we got in recruiting, team outlook, key players, and the like.
But I hope you'll end up reconsidering Dac. In reality, no one really knows for sure how the game will play out once it goes live. You just can't predict that from Beta because it has a lower population, and because people are trying different techniques. I hope all of the old coaches who say they are leaving will keep this in mind.
I think the new version has a LOT more strategy to it, and that gives good coaches like you an opportunity to separate themselves even more from others. It has not been very complicated for me to learn, but there are way more ways for a smart coach to win recruiting battles in this game, especially against higher prestige teams. It's really fascinating to me - I really do love it. There are still some things I would like to see happen, but by and large the way it is in the current version after evolving through 4 beta seasons is quite a bit different than it was when it started. So, I am not sure how active you were, or how many beta seasons you went through, but if it was just a season or two and you were not that active, please try it when it goes live for a few seasons. You might end up at that point thinking how glad you were that you didn't give it up.
