I watched the game again studying the OL.
Stork will win the starting C job, BEFORE half way thru the season. He might even share time or start in Game 1.
Halapio needs seasoning on the PS.
Kline was only average. He got pushed back on pass pro, and didn't really open any holes. But he is a keeper.
I was impressed with Devey's play at LT. He might take the last spot as an emergency swing tackle. He might free Cannon to start inside.
Fleming did well at RT. He would make a fine and better RG in my estimation. He probably needs some seasoning, but not much for RG.
Cannon needs to play. He is the third best Offensive lineman and its unfair to hold him as a backup tackle.
I have the roster as best to weakest as Solder, Vollmer, Cannon, Stork, Connolly, Wendell, Kline, Fleming and Devey. I'd carry 3 on PS with Halapio, Barker and Cave in that order.
