You've been consistent about predicting Iowa will make the tournament even if you've picked a few individual games incorrectly, but it's do-or-die time for them now. If they're going to go 8-3 for the rest of the way, they have absolutely ZERO room for error. With 11 games left, I think the likelihood if getting an "unexpected" loss is pretty high, which will require a high-quality win to erase; the problem is that Iowa probably won't have many opportunities for a win like that. The Illinois game won't mean nearly as much as it would have a month ago (even if Iowa wins it), and Minnesota's skidding pretty hard, too. Winning at Indiana would obviously be huge, and beating Wisconsin again would be solid...but it's very possible that Iowa might not even play more than one top-15 team for the rest of the year.
Their soft schedule is a double-edged sword; they can wrack up a lot of wins and make their record look good, but they also run the risk picking up a devastating loss or two, digging themselves into a hole that they can't climb out of.
I like your prediction--it's very ballsy--but even with Iowa's weak schedule, they're really going to have to play a 1.5 months of rock-solid basketball if they plan on pulling it off.
