A common trend in the modern NFL is for teams to sign highly experienced veterans to pair with rookies who go high in the draft. This way, the younger guys can learn the ins and outs of playing the position professionally. The Chicago Bears have actually enacted this approach twice. They signed Mike Glennon to pair with Mitch Trubisky in 2017 and Andy Dalton to pair with Justin Fields in 2021. Unfortunately, both situations proved toxic. Glennon was turned off by not being warned the Bears were taking Trubisky.
