Well if you don't think they are going to be at the level of those players (and they most likely won't, since you're talking about basically two HOFers), then there's really no point in giving up anything for them. Entirely possible that Bowser or Williams could be the Suggs heir apparent. And based on the trade value chart, it would have cost a 3rd to move up from 16 to 14.
Bowser and Williams Combined could be Suggs heir apparent. And notice the quotation mark around the next Ed Reed. There's almost a 0% chance that Hooker becomes as good as the best player in his position in the history of Football, but his massive upside and similarities and we could have someone as close as you can get. The 3rd we spent on Williams could have been used to move up for either (Even though I think Williams is massive value that late)
