We really couldn't even afford to have Big Baby out there even last season. He was a well-below average player whose lack of rebounding and shot happy ways really hurt the team.
I don't know if everyone just has a very short memory, or if they have no idea what kind of players come off most teams benches. Davis struggled down the stretch last year, but overall, he was one of the top handful of big men coming off the bench in the entire league, and through the first 3+ months of the season, he was a legitimate 6th man of the year candidate.
Now, that doesn't excuse the egg he laid in the playoffs when the C's needed him most, and I think perhaps a change of scenery might be necessary here, but I just think a lot of you are expecting way too much, if you are expecting the C's to find anyone better than Davis, particularly if you also want them to find a starting quality center.
Anyone who wants him gone, just needs to prepare themselves for a Tony Allen scenario. You may be happy that you don't have to watch him anymore (I know I am)...but the skillset is not that easy to replace.
