To Brett Kollman Foskey is a tier 3 edge rusher

Kollman informed? Isn't he basically a blogger. Does he have any scouting or related experience?
He's pretty good, but as mentioned he makes his assessments sort of in a vacuum and sometimes doesn't come off that assessment after the player is set into a system, while his partner on Bootleg tends to look at players in the context they find themselves in.

Interestingly I'm listening to The Athletic draft wrapup podcast right now and they just spent seemingly 10-15 minutes (at about 1:20:00 mark of Day 2 wrapup) talking about how Foskey is exactly right for what the Saints need their edge guy to do, especially the edge opposite Cam Jordan, whereas it would be perfectly understandable were Foskey not even on the board of some teams who want their edge to do something totally different. By the same merit they could see a lot of the smaller edge pass rushers as not even being considered by the Saints because there's no way they could do what would be expected of them.
