Due to limited roster size and the top-heavy talent of the NBA, many undrafted players never get a chance to play in the league. It takes a stroke of luck for them to even get a shot.
Take Cavaliers guard Matthew Dellavedova as an example. The man affectionately known as "Delly" is one of four undrafted players competing in the NBA Finals – Cleveland's Timofey Mozgov and, although they're unlikely to see the floor, Golden State's Justin Holliday and James Michael McAdoo are the others. Dellavedova played for Randy Bennett at St. Mary's and Bennett played with former Cavs GM Chris Grant in college.
