I really like what CBSSports does with their team by team comparisons. It really allows you to see how teams have the resume they have. Pick any 2 teams and see how they breakdown.
Dayton was fine until losing to Duquesne - that put a sub 200 loss on their resume. Dayton's issue was they don't have many good wins. TX A&M on a neutral court is their best win. Their other 3 Top100 wins are at home.
Davidson is worse. They don't have any good OOC wins. They had 2 sub 100 losses.
George Washington has spent most of the last 2 weeks playing themselves off the bubble and will probably need to win the A10 Tourney to get in.
The committee tends to like to see road wins and it also tends to rate Top 50 wins higher - that's where the A10 teams are coming up short against some other bubble teams. I still think probably 3-4 A10 teams get in, but none can afford any losing streaks right now.
