Exactly. The MAC is currently 15th in the NET rankings (between Patriot League and CAA). Drake, out of the 11th ranked MVC is 16-1 with a low-30s NET and is widely considered to be very bubble-ish, but nowhere near a lock. The sad fact is that in college basketball today, fans love to see the "Cinderallas" in the tournament, but the powers that be continue to move the goalposts, making it harder for teams outside the P5 to get in without winning their conference tournaments.
That being said, absolutely right the MAC sucks this year. 7 teams in the bottom half of the NET rankings and only 4 in the top 100, paced by Toledo's mediocre 61 ranking.
The Zips have a maximum of 8 remaining regular season games. Winning out would put them at 17-4 headed into the MAC tournament with a likely ceiling of upper 50s, low 60s NET rankings. Probably a 13 or 14 seed if we get the MAC bid.
