That's why we all have opinions. You can say Matt is worth it and Gym deserved it. I disagree.
2011 playoff year. Prior to 2012 before a lame duck year, you can see why he was extended. At the time, summer of 2012, you have to agree with that. And with the turnovers, penalties and just not having that one extra 4th Quarter play in 2012/2013, you can see why he was fired. NFL, Not for Long.
Stafford's deal is cheaper than most of the new QB deals. That is fact. Old rookie deal and restructures make people blind to this fact.
Rodgers, Flaccos, Big Ben, Brees, Matt Ryan and Peyton Manning got significanlty more. Brady did earn much more for many years but just took a very cheap deal at the end of his career (9 per).
Kaepernick, Romo and Cutler got more per year recently. And some of them didn't have extra years like Stafford did for the signing bonus.
Palmer (age) and Dalton got a little less. Alex Smith was close at 17 per.
Eli, Rivers, Wilson, Luck, Newton and Tannehill all on the horizon and I'm sure will be more than 17.6 per.
