Even if Jackson improved his game over the off-season. IMO the staff is looking for a different talent-set to be our starting post. Maybe even our future back-up post.I get that he probably won't totally tranform himself as a player, but to think after a year of Big 12 play, playing in Kyle Green's defense, and having the luxury of an offseason of work - something he didn't get last offseason - he couldn't improve his game not insignificantly is somewhat short sighted.
Our defense took a step back this year and the staff needs to rebuild the roster to be consistent with the desire to be an elite defense. That means a post with the quickness to be an effective trapping defender. It probably also means a post who can be a shot blocker and upper tier rebounder. If the staff felt Jackson could be that guy, then IMO he would be back.
