Of the new guys, Harvey is the most important one. The Steelers were connected to him in the draft, and he probably should have been drafted by someone. He’s a bit small but is extremely fast and hard-hitting, so the Steelers could use him in special teams. Charlton played quarterback for Temple before moving to tight end, so who knows what the Steelers might do with him. The others weren’t really highly-regarded prospects.
So the big undrafted free agents so far are probably Saunders and Harvey, and perhaps Gray. Steelers Depot made a similar observation, but it was clear to me as well.
