Dude. You're wrong about Hanson. He was a great player, and a very good athlete. He'd translate just fine into the modern game because of his athleticism, in a way that other older UConn guys wouldn't. You ask the question: what does that have to do with the draft exercise. I'll ask the same: what does the fact that he didn't make the Jazz have to do with it?
And the Yankee conference wasn't as good as the Big East, sure, but players like Doctor J came through there. Obviously Hanson isn't Erving, but you devalue Erving's stats when you devalue Hanson's. I'd say it's more likely that Hanson's game didn't translate well into the NBA than that anyone pre-Big East would probably not do anything (actually, really, anything pre-Calhoun or so, since you dismiss Thompson as well).
The mid-70s weren't nearly as bad as you are suggesting. 1979 had a Magic-Bird NCAA final. Hanson's career overlapped with David Thompson, Bill Walton, Len Elmore, Adrian Dantley, John Lucas, Scott May, Bernard King, Phil Ford, Bill Cartwright, Cedric Maxwell, Mychal Thompson, and Larry Bird.
And the NABC had Hanson on one of their All-America teams. That players like David Thompson flamed out a bit in the NBA doesn't mean that they weren't great players.
I guess, though, we'll leave this up to the voters on Wednesday.
