I’m interested in finding a comprehensive grade list or ranking of the best long snappers in NFL for 2022 season. Some kind of performance based ranking instead of salary, etc. Can anyone direct me to one? For existing NFL rather than future prospects.
I have not seen a grading or ranking that is public. Pro Football Focus grades them but the grades are part of a subscription to their service and not sure how accurate they are as they tend to emphasize tackles. Best bets for the best are looking at who made the Pro Bowl which is voted on by players, coaches and fans and the All Pro Team that is announced at the end of the season
