If it weren't for Patrick Peterson, who is being billed as the best CB prospect in many years, the Broncos would go DT here. Marcell Dareus would be the likely pick if they did go DT because he's a great prospect with low-risk (unlike Nick Fairley, who is also a great prospect but with more risk). Given the Perrish Cox issues, the Broncos are unlikely to go with any high-risk prospects. Still, Patrick Peterson is a sort of Ndamukong Suh talent, those once-in-every-5-to-10-years prospects. The fact that he's also a really good returner means he could contribute immediately in multiple ways. The Broncos weren't a terrible return team, but they could stand improvement and Peterson would do that. Peterson would also be able to learn from Champ Bailey and eventually allow Champ to move to FS to make sure the Broncos get the most out of the new contract they just gave him. Finally, as noted above, this is a really deep draft for DTs. They could find some solid values in rounds 2-4 to address the position. Also, they're likely going to have to look to existing players to address that need (Amobi Okoye trade, anyone?). That's why we have the Broncos taking Patrick Peterson with the #2 pick of the draft.
