Just checking, I was little surprised that Ervin had only 3 scrimage touches,
While that might be possible Ervin received a total of only $137,500 in guarantees. The Packers could definitely move on from him after camp if they find an adequate replacement for him as a returner.
At this cost, I doubt that. After his first couple games, LaFluer said he was looking for offensive plays for him. They like him, especially at this price. In the off-season skunk works LaFluer might develop a couple more things for him or work in more of what he was doing into game plans.
In his 6 regular season and playoffs games:
3 carries, 35 yards
3 - 5 receiving, 18 yards
At least one of the incompletions, maybe both, was a downfield sideline route where he would have been high in the progression.
So, Lafleur featured him on a little over 1 play per game. Maybe he bumps that up a bit depending on matchups.
It's worth noting the game day roster is being bumped up from 46 to 48 with the requirement that 8 OL be included. I would guess this OL provision is to encourage off-loading a few starter special team snaps to a backup. You might carry 8 anyway if the backups don't have quite positional flexibility to cover two injuries in-game.
The long and short of it is there's an extra spot or two. The idea that you would like a WR who can do double duty in the return game to buy an extra roster spot is less important.
