Gotta say, Flynn today reminded me of (a 2003-2004) Hasselbeck, just his style his reads, the way he moves, quick decisions, etc. Even though I don't think Flynn had great stats, he looked good, looked ready, and I would be confident he could perform well if called upon with a game in the balance.
Flynn's salary cap money is a bit of a problem though, but probably not that much given that Wilson is making peanuts. I expect PC/JS to absolutely keep Flynn next year, or two, unless some unbeatable offer comes along, or a good backup gets drafted later in the draft.
This year, there were some sleeper gem rookies, several of which are now playing--Kirk Cousins in Washington, Nick Foles in Philly, and darned if there isn't one more I can't immediately think of (besides Ryan Lindley), but IIRC, all were 3rd-4th-5th-roundish or later. So I'd expect PC/JS will look to pick up a Kirk Cousins-type player in the the 4th-6th round in the next draft(s) and have a good backup plan already in place before even considering trading Flynn.
Oh yeah, and does anyone remember Gary Kubiak before he was the coach of the Texans? Remember what else he was? (Drum roll...)
Yeah, that's right, he was John Elway's backup. And every time that Elway missed a game for the Broncos against the Seahawks, it seemed like Kubiak came in and played as well or better than Elway would have, and the Broncos beat the Seahawks every time I can recall that Kubiak started.
2015 Adopt-A-Rookie: Frank Clark, bringing beastly effort to the LEO position.
