Tolzien and Flynn are both free agents after this year. I think TT kept both because he thinks Tolzien is potentially better, but he could lose Tolzien in free agency to a team that will give him a shot at being a starter. So he's keeping Flynn for insurance in case he loses Tolzien. If he's able to sign Tolzien as his future backup, then I think Flynn will be gone next year.
I don't understand the 2nd option in the poll.
