From Youngblood's STrib article:
It didn’t help that Whalen’s team is playing shorthanded. They are still without Gadiva Hubbard, who has yet to play following foot surgery. And top backup post player Palma Kaposi missed Sunday’s game with an undisclosed injury.
Besides poor 3-point shooting and poor in-the-paint shooting to close out the game, Kent points out the turnovers in the last 8 minutes and change (where we went from up 11 points I believe to a loss). I tried to count them from the play-by-play. I got the following estimate. 6 actual turnovers all within last 8 minutes. Plus 3 Wittenger blocks. We'll count 2 since Taiye got the rebound on one. Call it 6 + 2 = 8 turnovers in 8 minutes. That's on pace for 40 turnovers in a 40 minute game, and an average game goes 75-80 possessions. Call this game 80 possessions (just because of high turnovers). So (a) in the last 8 minutes they were on a turnover pace that, if they had done that for the whole game, they would have thrown it away (or launched a shot into a Wittenger block) 40 out of 80 possessions; (b) that's not good enough to beat Coppin State; (c) they actually did throw it away (or get blocked) on 8 of their (about) last 16 possessions.
As Kent points out, Illinois points off those 8 minutes of turnovers were enough to (and did) win the game for Illinois. Never mind the bad shooting.
Discount the following as 20-20 hindsight of course, but for those last 8 minutes, they could have fielded a team consisting of T. Bello (who was still rebounding and blocking and shooting OK), plus the 4 able-bodied bench players (Staples, Perez, K. Bello, Byrne), and most certainly that unit would have been capable of not throwing the ball away more than half of the time.
As many have pointed out, fatigue was certainly a factor during those last 8 minutes, also contributing to their inability to defend the three (of which Illinois made them all).
Ironically, they probably could have stalled for the last 8 minutes, assuming they could stall w/o turning it over and at least got an unblocked shot off. But that too would probably have been a bad idea. Rightfully, few coaches would try to stall 8 minutes with only an 11 point lead.
A better approach would be to play strong to win. Instead, it seemed more like they were playing "not to lose." And when Illinois started making (inadequately defended) threes, and they saw the lead swirling down the toilet, then it seems like they felt like they needed to live or die on mostly three-pointers (to make up for that last Illinois three, which took a huge bite out of their lead). That plus throwing the ball away every other possession was a recipe for disaster.
