Recently, I have been seeing a lot of fanpost comments such as "keep Beans for now" etc. For these, I hastily check the date of the post and find that it came after Biedrins' plummet. Biedrins isn't even playing right now, and these guys who post about him act like this whole year didn't even happen. Seems like they don't even watch the Warriors...
In addition, there has been much talk about the Warriors "acquiring a center." Problem is, there aren't a lot of good centers out there and we couldn't get most of the mediocre to decent ones out there anyway. Honestly, I think if we are looking for bigs, it should just be for a little depth.
Ekpe Udoh has showed some promise this year, and that was without the benefit of pre-season or early-season experience. I think that we already have our "center for the future" in this fairly young, athletic, cheap shotblocker who can shoot FTs and dunk.
Also, David Lee at center has been successful this year, and next season he may be even better in all aspects of the game. In my opinion, he has an extra gear that turns him into a quicker, tougher, stronger version of himself that he has only revealed in a few key games, such as his matchups with Garnett and Howard. He can't be guarded by centers, and when he is motivated, he can guard them. He also snatches boards fiercely (yes, even sometimes from his own teammates) which allows Udoh to challenge more shots.
Amundson has been bad for almost the whole year, but he is a high-energy bench big who has done well at times. He can come off the bench when Udoh gets tired or in foul trouble and Lee can slide over to center.
Basically, this trio of bigs has done a good job since Biedrins has disappeared and I believe it is reasonable to assume that both Udoh and Lee will perform better next year (with Amundson there is no clear reason to believe he will play any better, but he might).
So I think we are set on starting bigs. In my opinion, we don't need to go out and overpay a mediocre free agent center. We can get along with what we have.
