Who signs Jake Browning after this season?

Aaron Rodgers —> Matt Flynn
Dan Marino —> Scott Mitchell

I'm sure there are many more, but those are just 2 cases that stand out to me of injury back-up glory to free agent wonder to new team flop.

Can’t think of any where it worked out.
I wouldn’t say Mitchell was a flop with Detroit. He had a 4,300-yard season in 1995 and played four solid seasons there until Barry Sanders’ retirement finished that franchise for almost a decade and a half.
