Both had been battling injuries (McKinnie had a back problem and Ngata had a tweaked hamstring). Both were criticized for carrying extra pounds this offseason. But both are in totally different positions as they begin camp.
Ngata is assured of being a starter and is expected to have a Pro Bowl season for the fourth consecutive year. McKinnie, however, is guaranteed nothing.
While I would be surprised if McKinnie wasn't the starting left tackle in the season opener, the Ravens aren't going to give him the job. Baltimore has a better offensive line with a focused and determined McKinnie. But if McKinnie struggles in camp and in the preseason, the Ravens will cut him. They're not going to pay him $3.2 million this year if he is holding back the team.
McKinnie's play will stay a hot topic all summer.
