I live in Memphis and have seen Crawford live and on TV a lot.
He had games where he was on fire and games where he couldn't throw it in the ocean.
Regardless of how hot he is shooting he is a max effort guy that plays pretty good defense and can fill in at the point when needed.
Joe Jackson was the starting point guard and last year Memphis used a 4 guard rotation of Jackson, Crawford, Michael Dixon and Geron Johnson.
Crawford usually started at SG and got the 2nd most minutes of the four guards.
Crawford shot 36.9% overall and 37.3% from 3 and 65.5% form the FT line.
He had a 1.94 to 1 Assist to TO ratio last year.
I see him as an extra PG for training camp.
Delly should easily beat him out.
