Well, last game he had some terrific plays. Once Perk starts for us again, which I assume is a couple of games away, maybe even against Dallas, Shaq will be back and we basically won't need Semih anymore.
BUT... with that said, I like Semih very much, and of course there will be foul trouble, maybe even (G forbid) more minor injuries, when he will be needed, and I feel pretty confident about that even with Jermaine out. We are perfectly equipped at 4 and 5, and obviously Semih can start against almost all teams of the league (with Orlando, for example, being an exception).
