Yes on the last question. IMHO any of the top 4 seeds have an equal chance of winning the crown, given the records between those teams during the year. The first round always seems to be the hardest to get bye for some of the higher seeds. That is just Play-off hockey. Two years ago the 5th seed won the tourney.
Having said all that, IMHO Clarkson is in the drivers seat, as they are the hottest team coming in, but based on what I've seen live recently, watch out for Quinnipiac. I could see a Clarkson Quinnipiac final, and two years ago Quinnipiac knocked Clarkson out of the tournament in an upset.
