That's entirely speculative on your part. We have no idea what BMK's injury is or the extent of it. He could play Wednesday for all we know.
Secondly, I was the one who did the practice report earlier in the season. I came away impressed with Chinoso Obokoh's long term potential, but don't think that trying to play him now would be of much benefit. Here is a summary of my impressions from back in October:
- I was surprised that Obokoh was really about 6-8, which was shorter than expected
- Kid has a good frame for an incoming frosh; he can stand to gain some weight [and he will over time], but right now he's probably about 220 pounds
- At least in October, he was clueless when it came to positioning on either side of the ball
- Previous bullet point acknowledged, he demonstrated impressive rebounding / shot blocking prowess for a guy who was out there just running around. VERY impressive on both counts
- That said, my expectation for him playing in a "live" game would be that he'd be extremely foul prone, due to his physical approach and being consistently out of position
A lot of people are going to look at that fourth bullet point and think, well that settles it--we need to use this guy if it comes down to it. But I'm not sure that I agree. The center position is the focal point of our defensive approach. It might not be obvious during games, but they have major, major responsibilities when it comes to covering the baseline, stretching out to cover the foul line area, playing help defense when the wings get beat, and still bodying up when somebody tries to establish deep post position. I'm not sure that Obokoh would be ready to handle the role [similarly, I don't think it would "work" to throw Roberson in there and just tell him to go rebound]. Hell, I don't think that Grant is ideally suited for the role either, but at least he's someone that JB trusts.
Considering all of the options, I think the most likely [my opinion only] is that they'd go with Grant in the pivot, and work like hell over the next two weeks to get Roberson more comfortable out there, so that he can play one of the wing positions adequately.
Burning Obokoh's redshirt would be a contingency of last resort--akin to pulling the emergency 'chute. Again, just my opinion from having seen him play earlier in the season. Down the road, I think that Obokoh's going to be a very solid player for us. And I think the redshirt year is a great way for him to gain experience playing while maximizing his long term value as a program asset.
