Other than the fumble, RK did a good job. Had he been given the #1 receivers and plays to run that are designed to score and not just to kill the clock, he probably would have got us to the endzone.
What else did he accomplish other than the fumble? He threw catch-able balls but that's not to be confused with on target. This looks like the same back up QB from last season but with a different number. Yet, everyone's will to jump on last years QB was "light years" behind the starter but this one would look better if he had better receivers..
