The point I was trying to make is that by signing Fields, Day picked the winner of the QB race before the competition even started. By doing that, he all but guaranteed that Baldwin and Martell would leave. Why would these guys stick around if the don't feel they will be given a fair shot to win the starting job? Given that this is the current environment at OSU, I think this would negatively impact Day's ability to sign a stop-gap QB this year and QB recruits in the future.
To clarify, I think Baldwin and Martell left not because the didn't want to be the backup, but because the felt they weren't given a fair chance to compete for and win the starting job. Despite all of the coach-speak by Day that the QB competition would continue in to the summer, I think it would be a bit naïve not to think that Fields would be named the starter. Fields wasn't brought in to sit on the bench, he was brought in to be the started QB of Ohio State.
