From most to least important.
Dayton at Rhode Island - This is like our game against Maryland. If URI wins this one, they're feeling safely in. Without this, they're sorely lacking a signature win.
LSU at Arkansas - The road loss to Georgia knocked Arkansas from in to out. This would knock them down to needing a huge SEC tournament run. Their last game at Texas A&M isn't a needle-mover, so this is their big chance.
Minnesota at Indiana - The Hoosiers probably need to win their final two... They can maybe survive a loss to Wisconsin but not a loss here. Indiana won at Minnesota and has a lot more to play for.
Xavier at Providence - Honestly this is a toss-up. Both are on the 10-line in Bracket Matrix but Providence is lower and a home loss is more damaging.
Clemson at Virginia Tech - Clemson is on the very fringes of the bubble and could get in by beating VT and GT to close the year and claiming a big win or two in the ACC tournament. A loss here means they'll probably need to win the whole thing.
Northwestern at Wisconsin - Want the Badgers to stay Q1.
Villanova at Seton Hall - SHU can wrap up the Big East outright and give our win even more cred.
Virginia at Miami FL - Virginia is very safely in and probably a lock but a bad loss here cheapens NC State's win over them a bit.
Florida at Georgia - Florida's also probably a lock but the path to their missing out includes this loss. Even if they're in, a Georgia win further weakens the top of the SEC.
Bryant at St. Francis PA - Doesn't matter at all but these small-conference tournaments are one of the joys of March. Might as well root for a team that we're a bit familiar with.
