Not only these two, but, a lot of FR will see the field this year. My guess is a total of 10/11 players play this year. Special Teams is a great place for some of the younger guys with a lot of ability but maybe not enough to crack the 2-deep. As our depth increases, as should our ST's productivity.
One thing to keep in mind, the kids that are now coming in, either SO/RFR/FR will probably be put in earlier bc they are the new staff's "guys". I liken it to a kid at Christmas, you can't wait to play with your new toys.
