Not just this move, but he's weakened his team a bit in 2014 with recent moves, while improving his long-term picture. I'm happy about it, but IMO he underrated his chances at a title this year and has hurt his odds of winning.
I like what you're doing this year, for both you (this year) and the rest of the league (long term). You've assembled a clear favourite capable of steamrolling everyone in the playoffs, BUT you don't look quite like the juggernaut dynasty you looked like before the season. IMO you've increased your chances this year, while also letting the pack a bit closer going forward. Flags fly forever though.
