-- I think your reference to Cortez Kennedy actually argues against your point. In 1990 Seattle had picks 8 and 10. New England had #3. We traded 8 and 10 for #3. We took Tez, and they took LB Chris Singleton and DL Ray Agnew. They were solid NFL starters, but Tez is Hall of Fame and Ring of Honor. Now if New England would have picked Richmond Webb at # 8 and Emmitt Smith at #10, despite Tez's greatness it looks like a great trade, but those were literally the only two players, in the entire first round worth giving up Tez to get. The rest of that first round is a dumpster fire.
-- And you mention 1992, where we were so bad, even with Tez, that in 1993 we picked 2nd. New England was even worse, they picked 1st. Wow, that just gave me a Dan McGuire and Stan Gelbaugh flashback. Tom Catlin with the second best defense Seattle has ever had, but the most putrid offense in the history of football. But I digress.
-- Point being, if we get to #5 and there is no one there that we deem worth it, then yes, move down, but I would never knowingly pass on someone you think will be special, just to get more picks.
