That's overkill on Sampson and is taking the league in the wrong direction IMO.
I'd agree if he had an A potential. But players with a D potential can fizzle out fairly quickly.
Does anybody remember Oscar Ferry? He had an A- C- offensive rating, with an A- defense. He was 18 years old, and put up 25/10 his rookie year, along with 1.6 blocks, 1.3 steals, 2 assists.
Think about that. 25/10 with 1.6 blocks, 1.3 steals, 2 assists. He did that on 47% from the field, 77% from the line. That's an amazing rookie. He didn't ruin the league. Why?
He entered the league with D potential. His 5th year in the league he was a 17/7 player. 3 years later he was an 8/3 player off the bench. He was only 27 at the time.
Sampson with an A potential would be terrible. Sampson with D potential is fine and dandy. Keep in mind, he put up 21/10 with 2.4 blocks and 2 assists his rookie year.
It'll be a tough element for someone drafting that high. Certainly he's a slam-dunk #1 pick. But is he truly going to help a team that's that bad? If he only has 6-7 years of top-flight play in him, is that good enough for a team that's many pieces away?
