What "depth issues" do the Broncos have in the secondary that would require Rahim Moore to play corner? The Broncos have 4 CBs that could start on many other teams in Champ Bailey, Chris Harris, Tony Carter, and Tracy Porter..and a serviceable rookie in Omar Bolden.
You also fail to mention the Bucs have the worst pass defense in the league, on pace to be the worst pass defense in the history of the league. They will exploit Manning and pick him off? Pretty sure the top 5 QB will be the one exploiting the worst pass defense of all time.
