Palmer isn't just way better than the quarterbacks left with the Raiders—he's way better than Jason Campbell too. Again, we can go back to last year, a down year with Palmer having a bum elbow, and he's still better than Campbell.
Last year, Campbell threw for 2,387 yards, 13 touchdowns and eight interceptions with a quarterback rating of 84.5. If you project that over 16 games, it comes out to 3,182 yards, 17 touchdowns and 11 interceptions.
That's scarcely better than the 3,160 yards, 18 touchdowns and 16 interceptions the Raiders threw for as a team last year. With those totals, combined with the Raiders' running game, the Raiders offense was No. 10 in total offense and No. 6 in scoring.
If you put up Palmer's numbers from last year, a year that his elbow hung together by a thread, the Raiders would have been No. 4 in total offense and No. 2 in scoring. That would have done the Raiders a whole lot of good as they lost five games by eight points or less.
He surely would have connected on more deep balls, as Campbell connected on only 19 percent of his throws over 20 yards. Bad elbow and all, Palmer connected on 29 percent of his throws over 20 yards.
Also, Campbell missed guys who were more wide open than what Palmer had last year.
All this is proof that 75 percent of Palmer is better than 100 percent of Campbell.
