After checking the stats it seems as if Blake has the highest assist average of any PF in the league now. Among all forwards he is in the top 10 for his assist averages. I think that is pretty impressive and the stat should only improve as he gets better at passing out of double and triple teams. Also if we got better shooters to put around Blake there should be a huge improvement in his assist totals as well.
I think this is one facet of Blake's game that is overlooked by the media. A lot of people think that he can only dunk and rebound, but the numbers show that Blake is an excellent passer for his position and he continues to get better.
