I won't really consider it a loss if Valentine is not playing. It won't be used against them in March come seeding time.
The committee will acknowledge these games played without Valentine. A loss would affect them, but not to the same degree as if it had been incurred with Valentine on the floor.
That being said, this would be a tough road test for the Spartans even with Valentine.
That's a good point, as this is a tough road game anyways. It may actually be to their benefit Valentine is out.
