The psychology behind the undeserved goalie pull has never made any sense to me. You're already 2-0 down, to lowly Columbus, and trying to snap a mini losing streak. What more incentive do you need to wake up and start playing harder and better? If a goalie's having a bad night, then by all means yank him and give the other guy a go. If it then gives the team a little jolt and perhaps some renewed confidence that pucks will stay out of their net, fine. Otherwise, just let the netminder get on with his job.
Those practice top 6 lines are interesting. No reason why DeBrusk-Zacha-Pasta can't work, just depends if the chemistry is there. Poitras and Heinen have shown something previously, but Matt and Marchand have struggled to gel and seemed to be communicating on different wavelengths. Well not much harm in trying again with them plus Danton and seeing how it shapes up. What they've had the last few games certainly wasn't working.
