Your right its all part of the process, They are tanking.....
Miller is not great by any means but he could do more than hold his own against other teams 2/3s in the preseason while Teller could not. I sure hope Teller will develop into a starter and hopefully soon. Hard to think that next year they will need 4 linemen that are on the roster.
BTW, Joe said they should give consideration to playing Teller, like the have not??? Joe is in the business of writing stories not evaluating talent.
