Denver Broncos free agency 2020: Top 5 targets

Since the Broncos seem to have found their new franchise quarterback in the form of Drew Lock, it is more important than ever to protect along the offensive line. One player who it will be interesting to see where he ends up is Indianapolis Colts left tackle Anthony Castonzo. Indianapolis has a great cap situation, but maybe there is a way the Broncos can pry him away?

The Colts have the third-most salary-cap space at $86.1 million, so they may very well try to bring Castonzo back on another contract. Given that he has played his entire nine-year career in the NFL with the Colts, the team that drafted him in the first round out of Boston College, there might be a loyalty play here for Indianapolis. However, he will be 32 years old this season.

The Colts could look to replace Castonzo with a younger player, whether that be in free agency or in the NFL Draft. If he is available, the Broncos should key in on him because Castonzo is a consistently better player at left tackle than the much-maligned Garett Bolles. Castonzo isn’t a Pro Bowler, but he has been arguably the best offensive lineman in Indianapolis since 2011.

There is one other offensive tackle the Broncos should be in on, but that guy is more of a right tackle than a left tackle. Since left tackle is a more pressing issue in Denver, that might shoot Castonzo way up the Broncos’ free agency board. It seems likely that Castonzo will return to the Colts, but that doesn’t mean the Broncos should look to acquire him if they can.
