Pledger is outstanding for a 7'1 centre (or any big centre) at hedging and switching pick-and-rolls, which today is one of the most important jobs for a centre.
He is a solid low-post defender, good defensive rebounding, excellent offensive rebounder, good shot-blocker, ok mid-range shooter and decent at executing the high-pick-and-roll offensively, though the Breakers didn't utilise that last season as they did the previous year with less passing talent.
He doesn't have a good offensive low-post game, which is probably why some casual observers think he's useless. I don't see him ever being dominant in that area, few big men are, rather he is a guy you hit on seals or dives.
He needs to improve his touch around the basket, and he needs to be mentally tougher, if he develops a mean streak he will be a real defensive force, which we saw in patches the past two seasons.
Overall, he is a very good defensive presence and offensive rebounder, which makes he a very good centre when fit. Hopefully the toe injury isn't too serious.
