I saw one thing is that PJ has offered every senior to come back for next year, if they want to. So they've kept the 2021 commits low, to be able to accommodate that as needed. If Coyle gets word (and assuming it would be approved by regents) that football will be allowed to go over 85 for those guys, then they can adjust and expand the class. I'm sure he has a feel for what guys may not be interested in coming back (for example, Witham and Dew both started college football in 2015 !).
But I think he is practically begging the OL seniors to come back. Olson and/or Schlueter, would be huge to have back in 2021, with Faalele and perhaps Dunlap uncertain to return (at full strength). Notwithstanding that we have Guedet developing and apparently Ersery they can already tell is going to be very good.
