McKelvin makes our secondary complete? We'll now keep Brady and Co. at bay because of the McKelvin addition?
I don't care who your corners are, unless you get the push up front you will continue to get lit up. Don't get me wrong, good CBs help, obviously, but unless Stroud comes in and does what he is projected to do, not much else will change. If Stroud can't command double teams freeing up your edge guys (who aren't world beaters to begin with) your CBs will be exposed regardless.
As far as your sarcasm regarding OL, well, a C may not have been the pick @ 11 a particular G would have helped tremondously.
