This comment has nothing to do with Carter in particular. In fact, from everything I've seen and read of him he seems like an upstanding young man and he is certainly a talent on the field.
I think the portal is a mixed blessing for a lot of these kids. It's the right thing to do given the way coaches behave - as soon as a enough guaranteed money comes along they are gone. So how do you ask kids to sit out and give up a year of eligibility? I get it. But, how many young people will have the discipline to recognize that their best interest may be served by sticking with a program and developing? Many, maybe most, will not have the experience, patience or perspective to make sound decisions in that regard. Many will certainly benefit from the portal, but I have little doubt that many will make hasty decisions because something at a given moment didn't break their way.
