Very few QBs truly elevate a team, that's why they are so rare. I'm just saying Stafford hasn't exactly been set up well. He has never had a decent D and special teams. He has had eleven games in his entire career where he played with an RB who had a 100 yard rush game. Its negligent what they put around him.
Not saying that he will light it up, just think he has a chance to put a team over the top. Put it this way, I'd be shitting myself if the niners brought him in.
That's not true about the defense. For example, the year he choked away the playoff game against Dallas, the Lions had a top 3 defense in the NFL (#3 in PPG and #2 in YPG). As for the running game, that's a valid point, but a big part of that is that the Lions have been a very pass-first team during Stafford's time there. And they've spent their resources on being a pass-first team. Think about all the weapons during his time there (Calvin Johnson, Kenny Golladay, Marvin Jones, Golden Taint, Danny Amendola, Nate Burleson, Anquan Boldin, Titus Young, Eric Ebron, Brandon Pettigrew, Tony Scheffler, etc.). They're a team that has put a lot of resources into the passing offense.
All I'm saying is that Stafford for most of his career has fallen somewhere between below average and above average on the starting QB scale. He's not going to drag a team down, but he's not going to solve a team's problems either (unless that team's only problem is that they need average QB play).
As far as the 49ers are concerned, I won't be stoked if they get him. He's better than Jimmy G. But frankly, it's not the worse outcome for us. He's older. He has had durability issues of late. And he's not a great QB. Kyle Shanahan will maximize Stafford's abilities. But I'd be much more afraid of the 49ers landing Zach Wilson or Justin Fields than I am them trading their first for Stafford. They'll be tough with Stafford, but Kyle Shanahan won't develop him into an elite QB.
