This is a fallacy. NO ONE is suggesting Edmunds would get Darius Leonard money. No one.
IMO, the Bills love Edmunds and believe he is a key reason for why the Bills are a Top 3 defense. It seems certain the Bills will pick up Edmunds' 5th year and then very likely to extend him for around the Sportrac estimate: 5 years, $66,905,730 - or $13,381,146. Wouldn't be surprised if it's 5/$70.
If the Bills want to replace him with a Free Agent, that's what it will cost (at least). For those of you who want to replace him with a rookie, tell us how that's not a huge gamble, especially with the Bills in the late rounds and with other much more pressing needs.
