No, it's actually right. I looked it up on PFR.
Since week 8 at Denver last year:
26 TDs passing, 6 TDs rushing (32 total TDs)
11 INTs, 5 lost fumbles (16 total turnovers).
When you factor in the record and the yardage, he's a respectable game manager. Whether he was acquired for that or not is irrelevant 2.5 years later. He is what he is. Dude is not gonna be the franchise QB people thought he'd be, but he's also not one of the worst QBs who ever played an NFL snap like others think.
As bad as people think he is, you could -- statistically speaking -- do far worse (look at guys who've started here, like PJ Walker, Will Grier, Randy Fasani, Taylor Heinicke, Frank Reich for that matter). That's the scary part.
