A couple of things:
It ain't over until it's over, to quote Yogi Berra. I'm sure there are people on here that know bits and pieces, but not one of them knows the whole story. Probably his family are the only ones who do. Therefore, it's possible that he recommits in the future.
If he doesn't, I've been looking at the commits to Illinois, now that the head coach has been fired. We have done well there in the past couple of years. There is a kid that we had offered that is rated higher than Robert that we may have a chance of flipping. Nothing is for sure since, Kentrail Moran is from Illinois and may well stay with that team, but he is more of a straight ahead runner in the mold that Robert was recruited for. I know others have mentioned Tre Bryant and Thompson as possible replacements/flips, but I believe both of these kids were being recruited as the express back and I think Moe is a better choice for that position. Anyway, there are still options, some of which I am confident that we don't even know about.
