I'm sure more guys will enter the portal still, but I'll offer two things I think are relevant to remember.
1) It has often been the case that players from the previous coach did not buy in to a new coach and created resistance and a issues in the locker room. It is much better for these players to leave voluntarily right off the bat rather than stick around and spread a poisonous mindset.
2) Even when you "lose" in the portal, it doesn't mean the end of the program. We were considered losers in the portal last season, yet we still improved under Brent Key. Tennessee was probably the biggest loser in the portal in 2020, and look where they are sitting now. If we get the right guy for the job, we will be fine.
