As a Day 2 pick, the Broncos would like for Justin Simmons to contribute early, and in the wake of David Bruton Jr. and Omar Bolden's free-agent departures, he would appear poised to handle that role.
But sixth-round pick Will Parks could make a claim to that role. He has a different skill set than Simmons; he's a bit more physical and more suited to work in the box. But both are versatile enough to offer run support while dropping into coverage.
They had a knack for making plays on the ball during OTAs; each intercepted passes -- including one day where each had pickoff.
