If Jason Thompson becomes a better player than Bosh I will s*** in my pants. But I think the chances of that happening are really really really small, about as much as the chances that Don Nelson will win a championship with the Warriors in the next 3 years.
Forgive my cynicism but there is no way IMO that Thompson will even be able to match Bosh's level of play. This isn't taking anything away from JT - he has been improving and will become a solid player in the league. But as some have already mentioned Chris Bosh is one of the top PFs in the league at the moment, and one of the top players as well. Who would you take at PF ahead of Bosh if given a choice? Dirk maybe, Gasol (who's not really a PF but whatever)... I can't think of anyone else I'd rather have at PF.
All that said, I'm with you on not losing sleep over not getting Bosh. We need a quality frontcourt, and at the moment Bosh isn't the only option to achieving that, especially if we draft Cousins or Favors. He may however, be a possible piece to get us over the hump in the future.
Just for reference sake. Most of the revelant PF's around the league, listed by most PPG.

I may have missed a couple, but this is the majority of the main PF's. Kind of funny. Thompson's stats don't look that bad when you look at the overall picture, and consider that he's only been in the league 2 years. If he can improve by 2.5 points, and 1.5 rebounds a game, and play better defense, I'll be happy by the end of his third year.
As one can see, Bosh is clearly in the top five of all the PF's. Josh Smith would appear to be the best defender of the group. And Atlanta does play pretty good team defense.
