"Getting killed" was certainly an exaggeration on my part, but what does Jalen's actual height have to do with anything? He was a post player that averaged 15.3 ppg and 7.2 rbs per game. He was also a super aggressive rebounder, playing much more aggressive down low than his height. He also had a lot of issues to his game, but I'll take a player like Jalen on my team all day every day.
We also lose 6-7 House and 6-5 Caruso. Not post players at all, but that is size. So not only do we not really have a replacement for Jones (an aggressive, down low post player who can rebound and score), but we don't really have any size at all replacing House and Caruso, who averaged 4.8 and 3.6 rebounds per game, respectively. That's almost 16 rebounds per game between the three of them that we should be attempting to replace with sophomores and juniors on the roster. Only, we recruited (or couldn't keep) size so badly in the 2014 and 2013 classes that we only have one guy from those two classes combined who can play meaningful minutes for us (Trocha). Having Thomas would have helped too, but that's out the window as well.
I don't see how you can look at our post position - Davis, Trocha, Miller, Williams - and think "yeah, we will be fine there." How so? Are we suddenly going to have these great wing players that are going to score 15+ points per game or a steely-eyed veteran point guard? No. We've got sophomores on the wing and a true fish a point guard.
At least last year, when Jones or Davis picked up two fouls, we were OK. Now, what happens when Davis picks up two early fouls? Tavario Miller plays 14 straight minutes? We go small and move Hogg to the 4? Then who plays the 3?
We need another post player who can play immediately. A grad transfer with one year would be PERFECT. He would bridge the game to 2017-2018, when our post depth/skill will be much, much better.
