And I might add that in comparing Teague's and Marvin Williams's career trajectory to the point at which Utah obtained him, I don't see a big difference. Each had one fairly strong year, a very decent year, and a bunch of quite average years (going more on win shares than PER).
Marvin was a year and a half younger when Utah obtained him than Teague is now. Marvin had his worst two years as a pro with the Jazz, aside from his first two out of college. I'm not saying it's the likeliest scenario, but are we willing to take the chance that Teague is essentially the Marvin Williams of PGs if we trade for him?
I understand the best-case scenario for Teague. And maybe it's worth the risk. But I think the likeliest scenario is that Teague is relatively average or maybe just barely above that. That's an improvement this year, for sure. But is it worth Burks and a first rounder (or whatever the likeliest trade seems to be), along with the possibility of playing-time issues between him and Exum next year?
