While I realize this is your attempt to make some point about how historically bad it would be for Wojo to miss the post season for a 3rd year I think the Wiki and history make a far more interesting point at how similar Wojo's trajectory is to Kevin O'Neill's.
I take nothing from the fact that O'Neill's 89-90 team went to the NIT. In the first place the first year of a college coach's tenure is really more about the coach that left, not the new coach. Second a team that went 15-14 in a league not as strong as the current A-10 wouldn't be going to the reformulated NIT as it stands now anyway. For apples to apples that must be thrown out. So what this really shows is next season will be comparable to O'Neill's 3rd season when the team was 16-13 and just missed the "old" NIT. I think Wojo has a pretty good chance of bettering those numbers. As he has bettered the 90-91 performance with last season.
The other similarities are striking. Both coaches came in with a rep for great recruiting but unknown coaching. Both coaches brought in great classes. Both suffered through second seasons with young guards including point guards playing our of position.
I still think we have a decent shot at post season next year. But as others have said the difference between making the NCAA and missing the NIT based on the way teams are now selected is about 16 positions and probably only a couple games lost vs won. So even if we miss it this year I think its about what O'Neill did and he was in the NCAA the next year and in the sweet 16 the year after that.
