I don't see how we don't draft a O lineman this year. Maybe 2. Both Teller and Bitonio are somewhat questionable moving forward after this season.
Much is made of LT's, but IMO the most important part of a O line is the middle 3 in passpro. As long as the QB has that wall in front of him, allowing a step or two forward, as long as whoever is playing at tackle protects against inside rush, that step or so forward destroys the DE's angles and puts him right in to the tackles angle allowing him to just get in the way and ride the DE outside.
I think if you asked any QB, they would rather have a clean middle. A rush up the middle puts them in that "deer in a headlight" position. That's the panic position for a QB.
