I used the great Database of mocks at HailRedskins.com and the ongoing list of possible Colts targets discussed here to find (roughly) the chance any one of those players is available when the Colts go on the clock.
Times available at #59/Times available at #93. Out of 7
Laws 1/0
Johnson 1/0
Avril 3/0
Bennet 3/2
Adibi 5/0
Carlson 5/1
Forte 6/2
Howard 7/3
And here's where specifically the players are slotted in the mock drafts.
