Look at the past 20 NBA championships and list the key players to each. How many key players were PGs compared to shooting guards? In fact, how many teams in which the point guard was the best player on that team have won an NBA title.
Maybe Wall will be a superstar, but he might also leave in a couple of years. If given the chance to trade straight up Wall for Davis, I would take Davis.
