You have to play at least 30 minutes to get that many points, and with the core players getting most of the time he won't be on the floor that long. Also, if one of them goes down, it is very likely that they will sub in Biedrins to replace the missing player because of his experience and the fact that his size will match up better against starting PF's and C's. The only way that he gets that kind of time is if he miraculously becomes a SF and Burks is the sixth man which causes a hole bunch of other problems when it comes to the fan base.
