Well, 73% is probably his ceiling. I mean, can we really expect any improvement at this point? The real question is what is his potential floor.
.... I kid, I kid. Just wanted to see Punch's head explode.
73% is an insane good number. So is his TD/INT ratio over the last 10 games.
23 TD/3 INT - an almost 8:1 ratio. That just doesn't happen. The top QB's generally have are ~3:1 ratio (in the 2.8 - 3.2 range). An 8:1 ratio is simply crazy. (For the season, Brady was at ~ 5:1, Rogers at ~ 4:1).
KC is really just putting up amazing numbers in the passing game.
