Delly Vs Exum is like comparing apples & oranges!
Delly - Proven FIBA performer, Synergy with Baynes, Hard Working, reliable, however is having a down year for the Cav's (Although all the cav's are!)
Exum - Injured, Not Proven in FIBA, Shooting improving but still not great, will he even play as he is a chance to on the NBA scrap heap so another injury might kill his NBA career.
If your choosing Delly clearly will get the nod but is anyone else concerned that Exum looks like the only NBA player to never go near the weight room? Surely he can get a better "trainer" and access better supplements!
