My take on it is, I don't necessarily like it, but I don't hate it either.
If College sports truly is amateurism, it doesn't make much sense to force a kid to sit out a whole season just because he transferred.
It definitely opens up the door for kids to leave a lot faster for not getting PT, but they do that anyway & in all reality, those players won't be convinced regardless of what you say to'em.
It's usually better for your locker room to get guys outta there with that type of a mentality in the first place.
We tend to look at this stuff as always negative to Miami, but the same pros & cons benefit every program, we could benefit from this rule just as much as it could potentially cause problems.
It's all really just about how your Coach runs the program to begin with. Bama has a bunch of transfers every year & kids still line up around the block to sign with them.
This will affect middle of the road teams, for top programs it won't really matter overall.
