It's dumb because you're avoiding my primary points, but I actually can and will. You don't go from scoring 4.9ppg and 3.2apg as a freshman in a weak conference to JUCO to scoring 10.9ppg and 5.9apg in the BIG without help. Sure, he regressed his senior year, but Marble also emerged that year. So was it regression or was it more the emergence of a future NBA player?
See? You can argue anything. And this is a completely reasonable argument.
Getting back to my primary points: there is precedent for improvement and current guards on the roster can improve. You picked on the weakest link. I'll wait for you to argue that Marble, Jok, and Gatens didn't improve under Fran.
