An in-depth Kevin Fishbain article from PFW. Good stuff.
"The Bills don’t have to look far to find examples of teams having success with rookies playing prominent roles. When the Patriots had the best record in the NFL in 2010, starting CB Devin McCourty was in his rookie season, and that defense had several rookie contributors.
"But Devin McCourty is the last rookie to start at an outside corner spot in a playoff game. Seahawks OLT Russell Okung, who started in Seattle’s postseason games in 2010, is the last rookie blind-side tackle to start a playoff game. Rookies play roles on playoff teams, but it has been a rare occurence of late to see a rookie starting for a playoff team at either cornerback or left tackle."
