I think it will be the dreaded 12:30 Easter Sunday NBC game 2
I noticed last year that the first round had gone back to playing every other day.
i.e. (wed, Fri, Sun OR Thur, Sat, Mon, etc.)
That gives NBC four series to chose from the first week and four (depending on the length of the series) the second week.
If they follow that model again, we'd play Saturday night Game 2, and be in Philly for a potential game #6 on Sunday 4/22
Also, Wells Fargo Center has a Miley Cirus concert on Tues 4/22, so if it's Rangers vs Flyers and we play Game #1 Thur and #2 Sunday, we'd either have to play game# 3 monday on a back to back OR wait until Wednesday.
I don't think they would manipulate the schedule that much given there are other attractive 1st round matchups to show Sunday afternnon(bos Vs Detroit, Chicago vs St Louis)
Based on all of the above, I am betting/hoping game # 2 is Saturday night.
