Lets look at it this way:
Who is the best offensive lineman ever? Anthony Munoz? Willie Roaf? Bruce Matthews? Randall McDaniel? John Hannah?
Choose anyone - your personal #1 offensive lineman of all time.
If you were starting a franchise would you rather have that offensive lineman or would you rather have Warren Moon? Jim Kelly? Joe Namath?
Quarterbacks are so important that I'll take a great QB (not best ever) over the greatest offensive lineman of all time.
No player in this draft - as a prospect - is the "greatest of all time" at any position. I'll take a very good prospect in Geno at QB over a great prospect (debatable) in Joeckel, Werner, etc.
