I would wait to see what happens in game 2 before making any decisions. If NJ wins, then you could take them for a couple units to win the cup and hedge. If Col wins, take a look at IE's answer to series winners who win games 1 & 2. You'll get better odds on NJ if they are down 2-0 and you still don't feel comfortable.
If it were me I would just wait and see as you obviously got some rediculous odds for Colorado to win the cup as I put a bet on them preseason and only got 5 to 1...
