I disagree with this. Allowing wholesale replacement of portal guys would create an even greater disparity between the haves and the have nots. Schools like Clemson or Michigan or Bama could just bring in 25 guys, sort out the wheat and the chaff in year 1 and cut every marginal kid. Then just bring in more top guys and repeat the process.
It is going to take a couple of years to sort out how the new rules apply, and kids will start to figure out the risks and benefits of the portal. We’re not there yet.
I do think, however, that the four game rule should be changed. Now that we have the portal, I think that rule should only apply if you stay at the school where you played the four games. Hopefully that will eliminate kids hitting the portal mid season. That’s just bad all the way around.
