I think he got overconfident after the Wallace thing turned out to be accurate (in all fairness, he was really pushing that well before the national media mentioned even the possibility). Maybe he knew the Celtics were willing to spend, would go after somebody to make a big splash, and put it together that Sheed would best fill the Celtics' needs. He did a good job with it. But, oh, the Baby thing - maybe Davis met with the Spurs and Tanguay thought that was enough to go on. I think, though, he doesn't understand what other teams need, how other teams operate, and how much Baby is really worth on the open market.
