I voted no. Not because I think it's impossible, but just because I have a sinking feeling that Iowa is going to drop one that they can't afford to down the stretch - like @Nebraska, or the Illinois game maybe. And I'll go out on a limb and say that I don't think they will win at Indiana.
That said, I'm not one of those who is subscribing to the belief that Iowa needs to win its next 7 games in a row to get in the tournament, which would include beating Indiana AND winning 2 in the BTT.
My personal belief is that getting 4 of the next 5 (assuming a loss to Indiana), and not laying an egg in the first round of the BTT will LIKELY (not guaranteed, though) get the Hawks into the tournament. Better go ahead and win that 2nd round BTT game just to be sure, though.
The only real thing going against Iowa is its RPI, which first of all, is not the ONLY criteria the committee uses. Second of all, if Iowa continues to win, its RPI will improve. Several teams with RPI's in the 60's have been invited in recent years.. Iowa could be another such team.
