I believe Coach Hakstol will keep the team focused on one thing, and that's the Michigan game. He's consistently carried that message through all year, to success.
Jordy was interviewed on the FSN broadcast of the WI game, and he was asked about looking forward to possibly winning the tournament and he responded with the cliche "we're only taking this one game at a time", and then clarified that with "to be more precise, this one game with Wisconsin". So it seems that the players took it that way as well.
Secondly, while the Sioux celebrated the Final Five championship, they didn't seem to act like it was the end of the year. It wasn't an over the top celebration, and they didn't skate the trophy around the rink (to our chagrin) like we've seen in past Final Fives. To me, that's an indication that they are more focused on the task in front of them that celebrating the past. Finally, Hakstol's comments at the alumni gathering seem to indicate that while he feels good about the team's ability to play in the NCAA, they will not be looking at the future possibilities, and only focusing on the game at hand.
