The Chiefs are giving rookie Josh Simmons a shot at left tackle as Andy Reid praises his recovery and readiness for full contact

Since then, Reid has won 301 games - fourth in NFL history behind Don Shula (347), Bill Belichick (333) and George Halas - and become the only coach to lead two franchises to 100-plus victories and guided the Chiefs to three Super Bowl wins.

It seemed the initial plan was to rotate Moore and Simmons at left tackle, but on Sunday, Reid revealed a wrinkle. Starting right tackle Jawaan Taylor is one of three Chiefs who will open camp on the physically-unable-to-perform (PUP) list.
