I said "most" don't have Romo ranked in the top 15 based on the last 2 seasons. Some don't even have him ranked in the top 32 starters because he hasn't been playing and the last time he did he wasn't very good. Not in any particular order but Tom Brady, Aaron Rodgers, Roethlisberger, Eli, Winston, Mariota, Cam, Russell Wilson, Dereck Carr, Andy Dalton, Rivers, Brees, Matt Ryan, Flacco, Alex Smith, Andrew Luck and Sam Bradford would all be ranked ahead of Romo based on last season and this season.
Luck was injured most of last season but you'll have a tough time finding a current ranking that doesn't have him ranked ahead of Romo. I'm not saying all those QBs have been better than Romo over his career, some certainly haven't but most of those QBs would be ranked ahead of him based on last season and this season. You'll have a tough time finding a "current" QB ranking that proves me wrong based on the last 2 seasons. If you go back to the summer of 2015 you'll find rankings that have Romo in the top 10 but things have changed since. His stock went way down after the Carolina game and the injuries.
