I think another Tony can fill in on the defensive end. Tony Gaffney is a player that I think can make this roster as a defensive stopper and scrappy player. This kid was DPOY for the A10 last year, averaged a double double and was top 5 in the country in blocked shots.
The kid is 6'8, has a huge wingspan and is quick enough to guard the 3, and in a good defensive scheme could probably be counted on to guard the two spot in a reserve role. His stat sheet might not show a lot when it came to summer league and even, but he's pure hustle, will get second chance points and will play solid D. In college he was used out of position because of his height, but in an NBA setting I think he can thrive as a role player in the 3 spot.
