As things stand right now ... I feel the three teams to watch are Bowling Green, Central Michigan and Kent with regards to the MAC Tournament.
BG's metrics are strong, even if their record is not. If they play to their metrics down the stretch, they could make a push toward the 3-seed. That makes Tuesday's BG-Kent game critical for them. Kent can probably lock up the 3-seed with a BG win as they hold tie-breakers over every other team behind them. At the same time, while they have a strong record, their metrics aren't really that strong. If they struggle down the stretch, they could fall a few spots.
Central Michigan is on the outside looking in, but they have been playing well and are just one game out of the 8th spot with games vs. several teams that could be critical, including one vs. Buffalo, and one against Kent - a team they already beat. Keep an eye on CMU the next few weeks.
