Option 2: Brandon Allen

Allen is not a starting quarterback, but he could be a decent backup.

The best backups are guys who you rarely have to turn to but are capable of sticking around the organization for a long period of time so that if their number is called, they are 100 percent prepared to go into a game.

Allen could be that guy and you could even lump Brett Rypien into that conversation if he can step up and beat Allen out next summer.

Wouldn’t it be nice to have Lock and a reliable backup the same way the Broncos had John Elway and Gary Kubiak many years ago?

Kubiak was Elway’s backup for nine full seasons. In that time, he started a total of five games. But he was always prepared in those games and though he wasn’t Elway, he gave the team what it needed in his absence.

Option 3: Looking outside the organization

There are some decent free agent options available at the quarterback position this offseason, but guys like Teddy Bridgewater and Marcus Mariota are not going to come to Denver to back up a young guy like Lock unless they get huge money or no interest from other teams.

That isn’t likely.

That could leave the Broncos choosing from the likes of Colt McCoy, Chase Daniel and Mike Glennon, among others.

But one interesting option is Trevor Siemian, who could come to Denver for a reunion as the team’s No. 2 quarterback. Since being traded from the Broncos, Siemian has been a backup quarterback and that’s really what he should be, but he could be more than serviceable in that role.

Siemian is better than many fans are willing to give him credit for and the Broncos could do much worse in selecting a backup to Lock next season.
