in order for a player to be worth 2 first round picks you must be a pro bowl talent.
Sammy is a special player and sure looks like he could reach that level.
would i have made that trade ? NO
i prefer trading down and picking up second round picks (high value $/talent). i also prefer drafting big boy front 7 players in first round and going skill in second round.
having said that, without sammy, they don't win yesterday.
