Seattle got a better return for Russ.
Key difference is obviously that the #1 pick will be on a rookie deal for 4 years + 5th year option so they save a lot of money there and IF they think the guy they'll take at #1 is a future HoFer then it's probably a good move... but that Panthers team is terrible. Maybe playing in a bad division makes more sense for them but you only make this move for a QB. They must have someone they like.
