One of our best, Fletcher, was an undrafted FA. Westbrooks is a rotational guy for us now that wasn't drafted. We have a pretty good history of finding good players on the line and at LB in later rounds or FA.
I've been reading how some people would just take players off the board because they don't jive with a poster's desires. There are a lot of good linemen to be had in the draft at the last part of the 1st round, and you can traditionally find very good linemen where we are picking. Hoping that our current starters will play 16 games next year is just that- hope. Fortunately it seems the FO agrees with this as they are already making noise about not only needing to add depth, but plan for the future.
