But, if MacVittie RS this year then he could be the backup and still get significant reps next year. However, if one of them comes out as the real starter, then the chances of the other ever passing them (unless the one picked as starter is horrid) is extremely low. If the competition isn't an in season one, whoever starts, Schneider or MacVittie, will be the starter for years, unless they are bad.
I think the upside is much higher with MacVittie, so I hope he proves to be the better QB by next year, but if not, I imagine that means Schneider can be a pretty decent QB and won't give up the job.
