FWIW, PKM is right about Larkin. While his athletic numbers are great, you can't really compare him to Nate Robinson. Even though they both have about the same vertical, you can tell that Robinson is much more explosive. Now what I mean by that is that Robinson gets up quicker. It's like having two guys that both run a 10.7 in the 100 meter, but the first guy runs a 4.3 40 and the second guy runs a 4.5 40. Now Larkin isn't bad by any means, but these Nate Robinson comparisons aren't exactly legit IMO.
Larkin rarely every dunks (even though he can, kinda, has small hands), and doesn't finish nearly as well as Robinson does. He struggles running an offense, and his size is a limiting factor. I like him, but I like him as a backup.
