Burger has technically played 3 out of 4 days since he started the 1st game in Charlotte (and came out that game with a slight injury before being called up). We don't know what these guys are dealing with on a day to day basis and its not like TLR is straight benching him.
In my opinion he should've been in AAA to start, but I don't mind him (hopefully) getting a short stay in AA before the jump. Like I said in a previous thread in PHT, god speed Yolbert.
