Essentially the tier 1 EDGEs are Davenport, Landry, Key...and Taven Bryan at DT...
Chubb is Tier 2. What this means as far as his 3-cone is cincerned, which he did terrible at, is that chances are he will never be an elite sack artist. That doesn't mean he won't be a great player. It just means he's less likely to get to 20-32 sacks in his rookie contract than Davenport, Landry, and Key
