The argument, imo, isn't about the standard for qb play in general, but about comparing Taysom to himself...and he threw high, low, and behind his receivers more frequently than he did in other games. A few times he held onto the ball too long.
Also, most of his throws were short/intermediate routes...so he should have had a high completion percentage.
The most impressive throw was to Matthews in the EZ...but he was pretty open.
