This season is a loss, even if UConn somehow wins the American, which is unlikely even if the team finds its heart between now and the end of the season as Louisville and maybe even Rutgers are better than Michigan.
Thus, I would prefer to save Boyle for next year to 1) keeping his 4 years of eligibility for (hopefully) and new coaching staff next season and 2) saving him from bodily harm as any QB playing behind this GDL gem is bound to spend quality time in a hospital. I do not expect Joe Montana or even Dan Orlovsky; but, he is the best hope for the future right now on paper.
Thus, make it an open competition between Whitmer, Cochran & company (DeBerry, Ecke?). Maybe it will light a fire under the team or at the very least, will allow the new (hopefully) coaching staff to look at the tape to see who is worth keeping around next season.
