Indianapolis Colts: Pre-free agency 7-round 2021 mock draft

As mentioned in the opening, the retirement of Anthony Castonzo has created a pretty gaping hole next to Quenton Nelson on the Indianapolis Colts’ offensive line.

Castonzo was a longtime starter for the Colts and a reliable one at that.

The Colts might prefer a proven veteran option to the 2021 NFL Draft, but there are some really good offensive line prospects in this class and starter-caliber players that could be had on day two and maybe even early on day three.

It will be shocking if the Colts are not “in” on guys like Trent Williams of the 49ers or the possible Orlando Brown Jr. and Trent Brown trades, but if they are unable to find a starting left tackle option before the 2021 NFL Draft, they should have no issue finding a starter during it.

Dillon Radunz is not hyped quite as much as his NDSU teammate Trey Lance, but how interesting would it be for Radunz to come to the NFL and block for the blindside of Carson Wentz, another fellow Bison?

Radunz looks like a pretty scheme versatile player with a strong core, good quickness for a big man, and a solid anchor already.

He’s played a lot of football and with as much as the Colts are likely to establish the run, he’s a guy who would be a fit in that phase of the game right away
