Personally, I think something like ANY/A from Profootball reference is a better indicator of production. Just measuring total yards doesn't really tell you everything, since two equally talented QBs could be ranked different depending on play calling.
ANY/A rankings have Tyrod at 9th and 19th, averaging out to just about average. Which, the eye test tells me lines up. This year is down, imo, partially due to missing WRs for multiple games, especially deep threats.
Do I think Tyrod is a guy who can carry a bad defense? No. Do I think he is a guy that can win with an average to good defense? Yes.
We have talent on the defensive side (at least I think so). If our new DC can convince the FO that the defense will improve, I could see Tyrod coming back.
