As already as has been noted, several guys on this team are good enough and intriguing enough to fill the last couple of roster spots on the regular team. There even are roles they could easily fit.
Beasley actually plays almost the same game offensively as Melo now, but he might be a little better right under the basket. Three-level scorer, can do damage with his back to the basket when you have a team going small or want to slow pace. Except he's not going to dribble the air out of the ball like Melo and he's your ninth or tenth man, not your sixth or seventh.
Blakeney's scoring touch makes me wish we had a spot for him. TBH, I'm not sure if he might not be a better fit than McLemore. I like the Snell signing, but I still haven't quite understood picking up McLemore.
Brown looks like a player. So athletic, but he hasn't forced anything in summer league like so many young guys. Shot looks better mechanically than it did in college. I think he might really be the big beneficiary from playing with all the experienced guys.
