Jared Gaither is a worthwhile risk for K.C.

The Kansas City Chiefs have been stealthly during free agency, picking up quality players without much fanfare.

They potentially outdid themselves Thursday morning when the team announced they signed former Baltimore left tackle Jared Gaither.

There are plenty of questions, but if Gaither -- who is 6-foot-9, 340 pounds -- is healthy, he is a solid upgrade to their line. At the least, he is a solid backup who is recovering from back injury that kept him out of action all of last season. The Raiders jumped on Gaither early in camp and likely would have signed him had they been pleased with the results of his physical.

The Chiefs could be put Gaither in at left tackle and move Branden Albert to right tackle. It has long been thought that Albert could move to right tackle or Gaither could replace Barry Richardson at the spot. Or Kansas City could give Gaither more time to heal and use him as a backup to start the season.

Matt Williamson of Scouts Inc. loves the addition.

“If healthy and motivated, he is a Pro Bowl left tackle,” Williamson said. “He can also play right tackle, but he’s a prototype left side. Love the signing. He’s the final piece of their offensive line puzzle.”

Gaither is the third former Baltimore player Kansas City has signed this offseason, joining Kelly Gregg and Le'Ron McClain. The Ravens beat the Chiefs in the wild-card round in the playoffs last season.

Overall, I like the Gather signing. There is no guarantee that he is ready to go, but if he is, he just made a good offensive line very good. It’s a worthwhile gamble.
