Stafford stats against non-winning teams

I'm failing to find the analysis here that leads to a vast majority of the losses he listed not being stafford's fault. In most of those losses Stafford's numbers aren't any better than what I'd expect out of a backup QB. Those stats hardly look good for a QB in the mid 90's, let alone a post Peyton-era QB, where everybody's finding ways to play uber efficiently and without making terrible mistakes.
In a lot of those losses the excuse seems to be "well why couldn't his defense keep the points down?". How can his defense keep up when he's throwing interceptions and keeping low completion rates and/or low YPA rates, likely giving the other team short fields to work with? And "his defense sucks" seems to be the response too often when playing teams like the Saints, who's defense also sucks. You can't go +1 TD vs ints and expect to beat a team like the Saints in their best years. Or even the past 3 years.
At the end of the day, his stats against losing record teams isn't even that good. A 2/1 TD/INT ratio is NOT good enough in the modern NFL. Brady threw 14/1 last year. Rodgers was like 7/1 in a year where he wasn't very good the first half of the year. Matt Ryan's ratio was 5/1 and, up until last year, nobody considered him markedly better than Stafford. Even in one of his most inefficient years, Brees threw better than 2/1. It's 2017, not 1997. Stafford's stats straight up aren't good enough. And his playoff stats are laughable. Even if his team is bad, he needs to be better than that.
We can sit here and play the "his teams sucked"/"it's a team game" card forever, but every great QB in the history of the league has elevated their team's play to be a contender for at least a few seasons. Stafford was a #1 overall pick. He currently lays claim to the biggest Contract in the league. He HAS had years where there was decent enough talent around him.
If Stafford was to have a more modest contract I would be willing to cut him some slack. But if you're going to get paid like you're the best player in the league, you better PROVE it. Stafford has done nothing to prove he's an elite QB. I'm not sure he's even top 10 in the league right now. You can't take up that big of a chunk of your team's salary cap and then throw your hands up and say "my teams not good enough to win!". If that's the case then you need to cut your salary in half so your team can fucking afford some better players.
