I'm not from USM, I'm over from the NESCAC board to give you a little love, since this board is a ghost town.
When a player gets shut down against the only good team she plays, it's a solid bet she will not get first-team All-Americans. She'll be lucky to make any national team. Time will tell, though.
Bowdoin went 29-1 last year. I'm sure the addition of the former Ithaca assistant was a boon to the team, but methinks Bowdoin would have handled Cleary okay, regardless. That's what good teams do.
But back to the upcoming game. The reason I don't think it will close can be attributed to one of your statements above: "She's expected to carry the entire load for that team..." When a team is as clearly imbalanced as Ithaca is, it's a lot easier to cause them problems in the postseason.
USM lost to Bates and Bowdoin very early, and that's it. I'll take a stab and say 75-59, USM.
And I'll take the under on your line.
