the other interesting thing regarding the RBs is that 2 of them do play on special teams (both justice hill and gus edwards) which makes it not unlikely that not only will all 4 make the team but that they'll all be active on gameday too - it's also pretty clear from the video ive seen that they know they're a 4 man pack - they're grouped together a lot when one of them isnt going through individual drills and it's pretty clear there's a bit of a mentality there that's going to help all 4 of them
