Let me the voice of caution here. Remember the last time Jax got a talented but soft European? Kuckoc? Slava? Jax can make players worse.
He just beats them up for what they don't do (play D, rebound), screws with their minutes and wrecks their confidence. If he doesn't change his way with Gasol, you're going to see a shell of the former player, a guy struggling to find flow in 20 minutes of action.
Plus, while Bynum had a great 20 games there, it helped that he was an afterthought for opponents. He got points off junk plays. Now he's getting a rep, and will become a point of emphasis for the good teams, especially in the playoffs, and he may not overcome all that newfound attention. That's why guys backslide all the time in this league, they can't take on determined, focused opposition.
By the way, "Easy Tiger" does not mean what I think it means anymore
