As a CB2 he's worth it.
Go look around the league. Name me 5 better CB2s.
Alexander is washed and now has personal issues ('stepped away from football' recently). Trust me, if the could play, the Ravens wouldn't have traded him for a bag of footballs. And the Packers couldn't get rid of him fast enough, originally. The Packers. These aren't teams that have super-deep cornerback rooms.
If I remember right, you were on the Jalen Ramsey train too. That guy's making 25 mil a year to play rotational deep safety now.
They'll draft/bring in another young guy next year to compete for Davis' spot. This team really doesn't need reclamation projects. Like J'aire Alexander. Like Kyle Pitts. We're not the team that has to take shots on draft busts anymore.
