Nobody has ever heard of John Gilmore. Ever. A decent reputation for blocking would be guys like Vickers and McClain. Not John Gilmore.
Do you see any signs of Harrison slowing down with stats 100 tackles, 10.5 sacks, 6 FFs, 2 INTs? I don't think age is an issue with him. If his stats are down or he played scurried like Farrior, then we'd have a big issue. Farrior hasn't played at a high level since 2008.
Top 10+average+average+all-pro+2010 pro bowler sounds like a pretty damn good secondary to me. Especially when you consider our pass rush. Do you think this is true about our secondary?
