He's extended through 2020 and Snyder (and Allen) are focused on finding a location for the new stadium in 2028.

I think Jay stays until the team secures a location for the stadium. At that point, they'll probably be even more motivated to build a winning team because they don't want to open a new stadium into a declining fan base situation.

If the front office can execute (big question), they've got the time to still build a consistently winning team before they start selling tickets to the new stadium.

They could find a real GM in the next couple years and relieve Allen of all football duties. That GM could then replace Jay either in '20 or '21. Hell, the GM could replace the replacement in 2025 and still give the new guy a couple years to build some momentum before the new stadium opens.
