eberflus has, a few times, referenced the preseason snap totals rookies got in the past few years (mentioned stroud, richardson and others specifically, iirc) and suggested they'll look to be somewhere in that range with caleb.
i don't want him to play a whole lot, but i do think it's probably a good idea for him to at least have a few reps under his belt if only for the procedural stuff in the huddle and at the line.
