But the coaches asked Taysom to do very different things than the previous staff.
With Anae's offense the O relied ALL on Taysom Hill, so of course he put up better numbers. Ty's pro-style offense was much more balanced and didn't ask Taysom to rely so much on his feet, yet he still had 600 yds rushing which is no small feat for a QB.
Also, if Taysom had our WR's from 2015 (Matthews, Houk, Blackmon) in 2016 I guarantee you he would have been much closer to 3,000 yds passing than the 2,300 he ended up with. Our WR's last year had the most average performance of a WR group I've ever seen.
