What is the most common NBA number?

Single digit numbers are very common in Baseball. 3, 5, and 7 are typically taken on most professional baseball teams. However, there are no common boaseball numbers and no specific numbers for position players today. In the early days of baseball the players simply wore the number of their position, i.e. shortstop - 6, pitcher - 1, 1st base - 3, etc. Hence the terms 6-4-3 double play and so on.
