Who is/was the last best undrafted player in the NBA?
Any that became an all star?
Ben Wallace is the only guy that leaps to mind. Undrafted but was a 4-time DPOY, 4-time All Star, and was probably the scariest guy in the NBA in the middle of the 00's.
Brad Miller and John Starks were undrafted All-Stars too, as well as Ben Wallace.
Bruce Bowen, Raja Bell, and Darrell Armstrong have won some awards (All-Defesnive, SMOY, MIP) and were all undrafted.
Wes Matthews just got a max contract last season as an undrafted player.
Although he was drafted in the 2nd round, Hassan Whiteside is looking pretty good for a guy who was out of the league for a couple of years and signed to a minimum contract.
Outside of Whiteside (whose bargain deal is almost over), Thomas is probably the best value contract in the NBA right now (outside of rookie deals), and will be for the next few years.
