In the 11 games prior to Exum rolling his ankle (starting with Miami on Dec. 12th when he began receiving consistent minutes and was healthy), his per 36 stats:
pts ast trb fg fga fg3 fga3 ft fta stl to ast/to fg%
18.06 7.91 3.44 6.88 14.45 1.20 3.10 3.10 3.10 0.86 2.58 3.07 47.62

38.89 100.00
He was playing really, really well.
edit: Since my wonderful whitespace was stripped from above, let me just type this out: Exum was averaging (per 36) 18 pts and 8 asts on 47.6% fg shooting and 39% 3pt shooting with an ast/to ratio over 3 in those 11 games. He was actually playing 19 minutes a night.
