A wing gets the benefit of moving without the ball. They get the benefit of being defended by a bigger and usually slower player from the wing. When you rebound well for your size, you can crash the boards and get put backs, like Baer does (guess where Baer plays?). You can't do that from the 1.
I don't get it. This is basketball 101 stuff. Square peg - round hole, simple concepts. Only the worst kind of moron would start Shaquille ONeal at the PG position and then argue that he's a Hall of Fame basketball player, so everything will be fine! You can take a very capable basketball player, play him out of position and end up making him look like a bad basketball player. Through absolutely no fault of his own!
