This is NOT true. Never has been. It's a myth by his supporters. He is well below average. Always has been.
- This year in which he has been significantly benefited by dropped interceptions he is still 25th in the league in Int %
- Despite being 31st in passes attempted he is tied for 8th among QBs for fumbles lost
- He is "dead last" in 3rd downs converted per game
- He is last also in 3rd down percentage converted
- His is 1st in 3 plays and out %
In fact Oweiller has outperformed him in all the areas listed above.
He has had one of the worst TD (pass/run) to Turnover ratios (INT/Fumbles lost) for starters for years.
QBs that don't convert 3rd downs, that don't know how to get rid of the ball to avoid sacks and are not able to maneuver in the pocket are not good game managers. Those plays don't factor into QB rating (a flawed rating system) but they kill teams drives particularly with QBs that don't make chunk yardage throws to overcome them.
There's good reason why Tannehill is 11th in QB rating and 31st in QBR (only Rosen rated lower).
Of course, if the Jags offer a 7th round draft pick to get him and his contract off the books Miami should jump at the chance. Hell Miami should throw in the 7th for them to take him.
