So there's a lot of bad reporting out there on this issue, and consequently a lot of misunderstanding on this whole NCAA/CHL thing.
NHL preparing for possible CHL-NCAA rule change
"The NCAA is actively considering removing all restrictions for CHL players to play in the NCAA AFTER their CHL careers are done,"
This concerns ONLY players that have aged out of the CHL, not for draft eligible players. NCAA wants to recruit 20+ older players from the CHL into the college ranks. This potential rule change only hurts USports. It does hurt some Junior A clubs that recruit players, because a guy can just play in the WHL and go to US schools after he's done.
In your scenario with McKamey, that just wouldn't happen to jump back and forth.
I've seen people on this board repeatedly post the same wrong thing over and over (not you). The potential rule change has nothing to do with draft eligible players.
