5 of his 30 playoff games, or 16%, were in 2006.
I don't put much stock in just his 2006 performance either. But 30 playoff games is a decent sample size when you look at how consistent his PER has been during every year he's been in the playoffs:
2006: 5 games/ 11.3 PER
2009: 14 games/13.0 PER
2010: 11 games/12.1 PER
He hasn't just had a bad series or two which drag down his numbers. He's been consistently bad over three different seasons.
I might agree with you if I hadn't seen everybody but Roy implode in the Rockets series last year. We need to add role players like Horry or Fisher--guys who provide consistent performance in regular season and the playoffs. I don't like the idea of a guy who allows our team to play one way through the regular season, and then forces us to play differently in the playoffs. Every game is too critical to be forcing your team to adjust on the fly at that point. I mean, you have to adjust, obviously. But why add a guy you know is going to require you to change how your bench works?
I'd agree if I thought he'd be a long-term fixture on Portland's bench. For example, I really don't care that much if Andre Miller makes $7 mil or $10 mil/year, because we probably aren't going to trade him. But if we added Mo Williams, within a year he'll be considered overpaid and impossible to unload without taking back an equally bad contract. Derek Anderson 2.0. If we are giving up decent trade assets (JPEC) for someone we will likely need to trade again, I want that guy to also be a decent trade asset.
