Harris is our nickel back, but with a twist. Nickelbacks usually guard slot receivers, which Harris cannot do. In nickel situations, we sick Woodson on the slot receiver. This also keep Chuck close to the line, where he excels in pass rush and run support. Harris can jam the hell out of WR and is a pure man-to-man corner so we stick him on the lesser of the two remaining WRs. Tramon can cover 90% of the receivers in the NFL, so he is match up with the best outside WR.
Think Dolphins:
Woodson on Bess in the slot.
Tramon on Marshall on the outside.
Harris jamming the hell out of Hartline on the other side.
Shields slides into dime, which is the perfect situation for a green player like him. He was on the field way too much as the nickelback. Being the 4th CB will allow Shields to have time to talk to the coach between plays and make in game adjustments.
We shift Collins to what ever side the faster receiver is on.
