Gasol wasn't unwilling to leave the low post, he often moved away from it when playing alongside Bynum.
But Bynum's low post scoring ability was second to none among centers in the entire league.
If Howard had Bynum's low-post footwork, the hook shot with both hands, the soft touch, and the passing ability, Gasol would have no complaints at all.
However, Howard could hardly pass the ball; in his time with the Magic, he could forcefully score as a dunker, but that ability faded after his back injury. This season his turnover rate for one-on-one plays set a new career high at 30%, and a less than 40% success rate for back-downs as a center was a disaster.
The most critical point was that once Howard received the ball for a one-on-one in the low post, it signified the end of the play, and they might as well get back on defense.
