I think the three of Dennison, Benton, and Kubiak each have guys they’ve worked with in the past, currently on other rosters, that they’ve asked personnel/scouting to keep an eye on. And somewhere between cut day and week 1, they’ll monitor those guys’ availability… and if one or more of them shows free, either by being cut or buried on the depth chart, to make the appropriate move to bring him over.
I don’t think they want to make a move right now, because they’d prefer to see all they can from Penning and Udoh.
