Brohm’s choice was between Blough, in his last year of eligibility, with a ton of experience and so/so physical skills and Sindelar, who had greater physical skills and 2 years of remaining eligibility. I think it is premature to say how big a difference there is in physical skill between Blough and Green at this point in that Green has had limited playing time. I imagine there is some, but it is hard to quantify. What is interesting is that Brohm benched Sindelar, their quarterback of the future.
The original question was about whether there was a Power 5 team recently that had a quarterback competition that came to the wire where they split time the first game, and Purdue fit the bill. Also interesting is that after naming Sindelar the starter at the last minute, Brohm pulled him and only played him one more time, in mop up duty against Easter Michigan. Sindelar did not execute in the first half against the Cats, and Brohm essentially benched him and lost a year of development, though I assume Sindelar retained his eligibility year.
