Berrios bailed Rosier out in 2017.
BB8 made circus catch after circus catch that year that made Rosier look serviceable. Fast forward to 2018 and no BB8 = Rosier shown for who he is.
His decision making is too slow to be a P5 QB. There are plenty of guys with good arms in life but you need to have that fast decision making ability to play QB at a lace like UM.
