It doesn't have to be DLR vs Peca, they should never have brought back Pleks, only to waive him, if they were going to waive him then do it before DLR.
The question for DLR is can he get better and by how much. At 22 after being jerked around since he was 19 by this management and having one of the worst coaches I've ever seen in the AHL, he ends up career highs in games, assists and points. He puts up 12 in 55, on pace for 18. At 23 he's on pace for 21. He looked good at the WC's, would bring size, a good PKer to a small group of forwards.
Perhaps DLR never really finds his way but for a organization that isn't going anywhere any time soon, they should be looking more at youth then players like Pleks, DLO, Schlemko, Benn, etc.. So there's no harm imo to want the Habs to have given the ice to guys like DLR, Scherbak in the hopes that maybe they could put it together after being handled so poorly in the AHL for our future vs having DLO, Schlemko, Chaput, etc.. for if/when we are finally contenders again.
