Yes. 30 games are supposed to be the benchmark. However, without starting one NFL game, some people claim to know from draft night what you got.
Mills has played in 28 games and started 26 of them. So, he still has 2-4 games left to show his stuff to the naysayers. However, when you look at QBs getting a chance to start 30 games, it's not always guaranteed. For example, Mills has started more games than Ryan Leaf (21), Johnny Manziel (8), Jamarcus Russell (25), Matt Leinart (18), Jake Locker (23), Dwayne Haskins (13), Drew Lock (21), Josh Rosen (16), Mason Rudolph (10), Paxton Lynch (4), and Brandon Weeden (25).
Shoot, many here were touting Nate Peterman who only started 5 games to show his stuff. Maybe, Caserio should sign him.
