There are a lot of good points being made about the polls. I think Penn State should definitely be ranked higher, and I'd love to hear why they aren't, beyond the standard "well, they're CHA". So what? Mercyhurst and Robert Morris are CHA, too, and one or the other is usually ranked every season. I wish this Penn State team had the schedule of some teams that are ranked above them. Look at Northeastern's schedule: Maine, New Hampshire, Merrimack, Holy Cross. That's 10 of their 17 wins this season (New Hampshire also took them to OT, and ended in a tie as well). Three more were against Providence. That's 13 of their 17 wins, against teams I think Penn State would beat, too.
I think the voters have been voting for the same handful of teams for so long that they don't know how to add a new team into their thinking. That's understandable. Penn State could be having a "one off" kind of season that they can't repeat. I don't believe that for a second, but voters might think so. So, like Lindsay said, it will be up to CHA teams next season (if it's back to a normal season) to take care of business with non-conference games. It's going to take some time and consistency for Penn State to be in the mix on the national level. For this season, though, they're better than #8.
