I like to do redrafts from the Draft-Tek site.  They already have a 7-round mock available, they constantly update their player rankings, their rankings are pretty accurate, and you can use their simulator to come up with good ideas.  By redraft, I mean using the site's projection of where various prospects will be selected to decide what I would do if I were the Colts in that situation.  Here's what I came up as our draft:

1) Gabe Carimi, OT, Wisconsin
2) Mike Pouncey, C/OG, Florida
3) Jurrell Casey, DT, USC
4) Rahim Moore, S, UCLA
5) Zane Taylor, C/OG, Utah
6) No Pick - used for Justin Tryon
7) Lawrence Wilson, LB, Uconn
7) (Compensation for Tim Jennings???) Jonathan Nelson, DB, Oklahoma
