Just to introduce another angle though, it's possible with some guys (i.e. Darby, Tee, Deontay) that said before they committed they were going to take all 5 OVs the staff might have been like "sure, that's cool we understand." With Perkins, because we have a number other OLB targets and such, they could've given him a different set of rules. Like "if you commit, we want you 100% committed not looking anywhere else... and if you want to take visits we're going to be looking at other guys." I mean who really knows? But that's plausible and it's similar to what we told Justice Hayes (i.e. we told him we were still going to be recruiting other talented RBs like Savon Huggins and he was "OK" with that... until he got ignored on a visit).
More likely than not though, which is what I think you're alluding to, he probably doesn't have his grades where they need to be after Q1 of school and is looking at other options... and if his grades magically come up by semester than maybe ND is an option again.. if we have a spot open and he hasn't committed somewhere else. Remember, his offer at first was delayed by waiting for his test scores to come in, so there is more than a little smoke between that and the rivals report that the classroom played a factor here. But it's still all conjecture.
