Steve Wilks would have lasted about as long as Frank Reich did. He's had two DC jobs since leaving here and was fired from both; let's not pretend he's the second coming of Vince Lombardi. Would he have been better than Frank Reich? Of course, but that's not saying much.
Darnold was a free agent after 2022 and was highly unlikely to choose to re-sign here under Wilks or anyone else. And even if he had, he would never have developed into what he is now.
The difference for Sam Darnold was the year he spent as a backup on San Francisco under Kyle Shanahan and then going to Minnesota under another offensive guru in Kevin O'Connell. Had he re-signed here instead he would be a backup QB on some random team right now instead of preparing for the Super Bowl.
Do you think it's a coincidence that we had both Darnold and Baker Mayfield and neither produced here, but both became franchise type QBs after leaving for better situations elsewhere?
