Bogut was slow but won a championship with the Warriors. Zaza isn't quick but won a chip. You sometimes need a true big on a team. And we saw during last season, that Papa is able to protect the rim and rebound, he even hit some smooth jumpshots here and there. What's happening now is, that the Kings for whatever reason decided to still play offensive sets, that were implementent when DMC was still with the team and therefore ask our bigs to post up or make plays out of the high post. That's way beyond Papa's skill level. In a lesser role he might look quite serviceable.
Everbody is big on bringing the young guys around slow this time, because more playing time could somehow destroy their confidence. But then we ask guys to do things in SL, that aren't there for them yet. What's that going to do with their confidence?
