The Facts: The Broncos are signing quarterback Blake Bortles.

Diehards Line:Denver is expected to be without quarterback Drew Lock for at least two weeks and as many as five weeks due to a shoulder injury. Driskel looked acceptable while filling in versus Pittsburgh but is 1-7 as a starter and graded outside the top 35 passers in each of his two seasons with starts, per Pro Football Focus. Bortles is a modest upgrade over Driskel but nothing to write home about.
