Please note the number of offensive lienemen drafted 3rd round or later by the Skins that made it to the field this year. That would be zero.
Please note the number of OL not named Trent Williams drafted by the Skins that are starters anywhere in the league. Note that number is also zero.
Speculate on the odds of the Skins using their second round pick on an offenisve lineman. Also zero.
Multiply each of those together and you come up with the odds of having a good offensive line next year.
