Here's my take...
NOBODY KNOWS WHAT THE TEAM WILL DO IN THE NCAA OR NIT...
They could go in the NCAA and lose 1st round like last years team, or they could be a Cinderella like VCU last year.
Or
They could go in the NIT get embarrassed by a mid major, possibly at home, and leave a sour taste on the season. Or they could go on a run and beat a good team in MSG and win the NIT.
You just don't know what will happen and it's all hypothetical. The effect of being a Cinderella far outweighs the effect of being a NIT champion. You take the NCAA everyday of the week, because NO PROFFESIONALLY COACH OR ATHLETE is going in saying oh were gonna lose first round in the NCAA let's just go NIT.
Where do you think Iona and Drexel would rather go? They'll most likely be one and done, but could be serious NIT contenders. Do you think they'd prefer the NIT?
