The move looks fine to me, assuming that we DO NOT go to divisions - at least not yet. (And more importantly, not with the group of folks that are in my division. Don't know what you were smoking when you set up those divisions, Derek, but if I were you, I'd stop, because it REALLY impairs judgement.)
The selling point for me is PICK TRADES. That's something that I've always wanted to include - especially when you're staring down at the trade deadline, and you know you just need that ONE player to get you over the hump, but you don't want to give up your core - and even more especially because you know the Duncans and Nashes of your team won't be back next year.
I will say this, though: I hate nba.com as a site. In general, it's just awful. But on the positive side, we're not stuck if we don't like nba.com - we can always go back to yahoo.com next year if we don't like it.
I say we move.
