I highly doubt they’re giving the first team guard reps all training camp to a guy they want/expect to start at RT, especially a guy who’s got like 5 starts to his name. Mekari, sure, but faalele I would think is repping at RT if the coaches see him starting there, bad idea to not let the dude practice his position for his first season starting
100% - if this was more of a battle, they'd be splitting reps
only way this is possible right now is they're trying to build chemistry with rosengarten in the 2s - feels pretty unlikely though
