The reason I bring this onto the OSU thread is that I think that playing 4 lines versus 3 lines showed up in the final stretch of the UM/UMD game today, when UMD's top players appeared to have lost just a step as the game wore on, eventually taking a late penalty and giving up an empty netter as Minnesota's top players were slightly fresher. I'm a strong believer in playing 4 lines, especially early in the game. If nothing else, it will allow your top lines to have a little extra juice in the third period. In my opinion, Muzerall has elected to shorten the OSU bench too early in some of the games, particularly agains elite competition. If one's 3rd and 4th lines are total liabilities and are incredibly likely to get pinned in their own zone every time they see the ice, I completely understand not playing them. However, I don't think that is the case with the Buckeyes, and as pgb points out, when the lower lines are engaged, they can give the team a spark. Indeed that was the case against St. Cloud this weekend, with the 3rd line getting on the board first on Friday, and then 2/3 of the 4th line set up Skaggs (who had just shifted in) for the first goal on Saturday. I'm not advocating for the 4th line to be sent out in the third period when the goalie is pulled, but I think getting them and the 3rd line quality ice time throughout the 1st two periods will go a long ways toward helping Ohio State handle the teams they are favored against, and be able to compete late in games against the top tier teams.
