His general handle, and possibly impacts on his passing and catching may all be impacted.
Just think of STAT and his bandage wrapped hand in the playoffs... more than a few fumbles.
STAT had a huge laceration in the palm of his hand. Did you see that tweeted pic of his injury? That **** was vicious. Melo has 5 stitches in his finger. If he plays, its shouldn't effect him too bad. Guys play with messed up fingers all the time in this league, Kobe did it for like 2 straight seasons. Ronnies doing it right now.
