I'm not sure jenkins is in the same shape as when he ran 13.18, he was in unbelieveable form when he ran that!
He does however appear to be a track runner over xc runner, so if he finished that high up at ncaa xc chances are he's going to be beating most of these guys on the track if that's his best surface.
Will be interested to see how he gets on, i'm looking forward to seeing what he does once he's finished at Oregon - will he move to the NOP as can't see him running under Schumacher, seems like a different type of runner and to be honest a level above most of that group barring Jager and a couple of others on a very good day.
Seems like a few are staying post-collegiately with Powell sponsored by Nike (dunbar) so wouldn't suprise me if Jenkins and Parker Stinson also go down this route and all continue to train together with Cheserek.
Training with jenkins every day must certainly be helping Cheserek rather than him running everyhting solo as he's so far ahead of the other ducks, so i guess it makes sense for Powell, Nike and Oregon to try and kee a few of them together sponsored and helping Cheserek finish his legacy as the best collegiate runner in history.
