Nathan was arguably the best QB on the field last night. I couldn't believe it either.
A.J. took a sack first snap, attributed mostly to the second string O-Line having jitters, but both he and his O-Line recovered quite nicely. If you take him recovering from that into consideration, an argument could be made that he was tied with Nathan in regards to performance, as overcoming adversity is huge in QB evaluations.
Josh had a tough night as he was with the third string, and the drop off in depth from second to third string on our roster was on full display last night. Nothing another year of development and another good draft wont fix though. All that being said, I would LOVE to see how Josh performs with better talent around him...
