If Michael were not 4th string in 2015 I'd be unsure giving a ride to a grad transfer. But he's yet to seriously challenge for PT, even with his size. I had hopes for him with his arm but he needs a big jump in many ways or Merchant/Jackson will be even younger options...also with 0 total yards of career offensive production. Vs a grad transfer with over 1,500 offensive yards for his career.
Some say in the NFL, until you have a franchise QB, you should draft a QB each year til you find one. And in college, Srs won't have a 'next year', so play the best players you have to win right now. The 2016 Bulls have a lot coming back so find the best QB for 2016. If Rohach enrolls and wins it, only Michael loses out. Jackson will only be a R-Fr, can develop and learn and possible get a few snaps next year, then 2017 try to win the job as many suspect he is our future QB.
