The Indianapolis Colts continue to make noise, and this time it's with the Donald Thomas signing.Donald Thomas is the former offensive guard of the Patriots, who started and played very well this last year. He was one of the better lineman on that Pats team. He's young, athletic and strong, which makes for a good lineman.Thomas can start from Day 1 at the guard spot, considering the Colts have bad guards. He would most likely play right guard, but left guard is also an option.This is the 4th signing of the day for the Colts. (Offseason Central)The details are to be announced.
