There isn’t a long history of the Colts bringing in big-named free agents. They typically build their roster with a sum of their parts approach. Because of that, they typically steer clear of big name guys. But that gets you thinking; who is the biggest name the Colts have ever signed?
The biggest names have come relatively recently in Colts history. Ryan Grigson tried to make splashy signings when he was the GM. He signed several free agents with big names attached to them. Unfortunately, most of them didn’t work out.
Grigson signed players like LaRon Landry, Greg Toler, and Frank Gore.
