Trading now would mean trading at a lesser value than nearer to trade deadline.
Teams are well aware of, for example, Monahan’s injury history, I doubt much are willing to trade prime asset right now knowing he’s probably getting hurt between now and the playoffs. Much less risk, because it’s much closer to playoffs time,of injuries once you get to the trade deadline.
And I know it’s usually better to get something now than nothing later but Habs have plenty of 2nd, 3rd and 4th round picks in the comings drafts, i’d rather they gamble and wait to get a 1st than getting another day 2 pick.
