Disagree with most of that being relevant to Lowry. What team is going to succeed with a center who can't rebound or hit close in shots, inconsistent PF play, and SF/SG that can't consistently shoot the 3? I mean, you could put LeBron on this team for Lowry and they aren't winning a championship (and, quite frankly, the Raptors are worse than what LeBron had around him in Cleveland).
So basically Lowry could be a good PG, but only if...
1. Valanciunas develops into a solid C, capable of cleaning the offensive glass and hitting short jumpers consistently
2. Davis/Amir play consistently as starting PF, like they did yesterday (and no long 2's please... looking at you Amir)
3. SF & SG both need to be upgraded to players who can consistently hit 3pt shot (ie: NOT DeRozan, NOT Fields, but possibly Ross eventually)
