That doesn't make a whole lot of sense. Olesz is on a one year deal, Tedenby is still a RFA 1st round pick. On a team that sucks, the choice is obvious. Let him play and see what happens.
He doesn't need to be waived for roster reasons unless Clowe or one of the defensemen come back. Tedenby and Josefson were already on the roster, if Zajac and Elias play two guys in the lineup come out and go into the box. Obviously they made their decision on one of the guys coming out of the lineup.
Actually even with the defensemen, it's not like Merill is going to be able to play anyway, so he'd just go on IR and collect a paycheck for awhile, so really the only move that requires a waiver is Clowe.
Yeah I think they played Olesz to see what he brings, and decided to cut ties with him before his games played bonus kicks in
