In my mind, Udoh will never be anything more than a 4th or 5th big...in the absolute best case. And he's going to be making 4.5 million dollars next year...that's a lot of money to pay someone who's not likely to be in your 8-9 man rotation every night.
*also, my main point originally was that he is a guy they might be looking to move to clear cap or roster space. Again, you can get a cheaper depth big. They might also want some added flexibility with their roster. Whether it's trading for Bargs or a much better player, I do believe any team could have to take back extra players and money....and I pray that this would be a younger person like Udoh who could expire next year, than an old fart like Gooden who has a lot of money and years left.
**Basically, I agree with you Udoh has some potential, but it's not much higher than the level he's playing at. I see no reason the Bucks would make keeping him a dealbreaker if they had the chance to make a trade they like (again, even if it's not for Bargs, just focusing on Udoh). But for a team like TO, or any team hoping to improve going into next year, Udoh is a much better gamble than Gooden, for example. I don't think any team willing to take Ilyasova's deal will want to take such an amount/length either. To me, this leaves Udoh as a likely option for them to dump because a)he doesn't seem to matter for their long term plans, and b) he's throw in other teams might want because of even limited potential and no long-term commitment....which is clearly why Milwaukee wanted him tossed into the Bogut-Ellis trade.
