'If John Miller, the former Louisville guard the Bills drafted in the third round, is going to come in and compete for a starting spot, dominating at rookie camp would be a nice start.

At the least, the Bills hope to see the powerful run blocker they drafted look like the strongest guy on the line of scrimmage throughout the weekend.'
