With their current production levels, if you extrapolate it out over 16 games, Oz and Gabbert would be around 14th/15th in yards, ~17th-20th in TDs, and around ~20th or so in Interceptions (lower is better).
That's average, and pretty much mirrors the year Big Ben has had.
Don't play dumb with the Gabbert gag, everyone knows what your are implying by it. If it was any other year for Gabbert, I'd agree but not this year. Keep trying though.
The Gabbert gag is implying he isn't a worthless QB by the standards of the NFL. It's that there is no room for error, and there are other guys showing more error in a limited duration. That is why it worked well with Mallett argument.
It works here because you have two guys, similar numbers, two teams at each end of the spectrum.
