First of all, Dice was sleepwalking the first half of the season, and Bonner was injured. And our bigs rotation was so stacked that we played Finley and especially Jefferson regularly at PF, while the other team was having a layup practice. In fact, we were SO STACKED, that Pop decided not to start Duncan to rest him, only to have to change plans midway into the game.
And please step away from the Ian bandwagon. You're the first to come up with excuses of why he's not getting playing time. Even today, he's barely able to even get any playing time on complete blowouts.
We could argue wether trading him was right or not, but there was no compelling reason for not playing the guy 10 mins a game while he was here.
