The potential thing is nice, but in reality do any of us really KNOW what kind of potential someone has? I mean, look at some players that went straight from high school to the NBA. I'm sure they all had great "potential" in the eyes of various scouting services, but how many of them actually make it? There are NBA teams that spent tons of money scouting these guys, signed them to multi-million dollar contracts, and then watched them bust.
The point being, I hope WIS puts something in place so sometimes the scouting reports are just plain wrong. A guy with low potential comes in and actually grows 6 inches and becomes an all conference PF. Or a can't miss recruit comes in and never improves much at all, despite a great WE and high potential on the scouting reports. That's reality.
