What a difference 30 minutes makes. 

After shutting out Yale last night, Princeton looked in command after taking a 2-0 lead, but back came the Bulldogs.

We were tied up at 2 after the first period, but the second stanza was all Yalies. 

Just 18 seconds into the period, Brendan Mason tipped a rebound past Zane Kalemba to put the Dogs ahead 3-2. 

With 9:42 left in the period, Yale scored on a pretty piece of puck-movement. Denny Kearney corralled the puck on the left wing, turned and put a pass right on the tape of Broc Little, who sprinted in from the point, took the pass right in front of the crease and deflected it past Kalemba to put Yale up by two. 

There were seven penalties in the first period, but the second period was much cleaner and more quickly moving. 

If Yale holds on, the teams will be back here for a decisive Game Three tomorrow night. 

And in the wonderful world of college hoops, Temple (A10) and UCLA (Pac 10) won their respective  conference championships, while Tennessee got clipped by Arkansas in the SEC semis. 

The Vols' loss likely opens the door for Georgetown to earn a No. 1 seed in the NCAA tournament if the Hoyas beat Pitt in the Big East championship game, which tips in 32 minutes. 

This, ladies and gentlemen, is why March is the coolest month on the calendar.
