Yet you see teams do it again and again. Just goes to show that ownership has different priorities... playoff revenue matters to them, as does icing a competitive team in order to sell ST's.
Dumba also needs to have a bounce back year to get anything much back at the TDL. He might fetch a late 1st if he is on pace for 30+ points, is healthy, and BG retains(not a big deal, IMO), opening up the market to Cup contenders. If he gets back to a 50 point pace, he could fetch a bit more.
My feeling is that we are going to be a good team this year who is in the playoffs, and that BG will not consider any move that will weaken the team going into the playoffs. I can also see BG re-upping him to a lesser, long term contract(say 6 x 5.25M), together with the dreaded NMC. A lot will depend on how, and how much, he plays this year.
