It could work out very well with this team overall. I was reading in the new Steelers Digest and they were talking about the possibility of drafting a CB in April. Taylor is a starter and he's got all the physical tools but still needs to get better at understanding the game; he's worlds better than he was in 2006 when Cowher benched him. Townsend isn't getting any younger but right now he's still the best pure cover guy we have. If McFadden can finally step up and beat out Townsend for the job it would allow Gay to step up the main backup role and allow Townsend to help out at Safety, with depth. He would make a great FS IMO; he's got great coverage skills and has a nose for the ball. Either way we end up with a versatile veteran who could step up and play either position for us if necessary.
In this day and age if you can gave 4 solid CB's you're doing pretty well but more realistically you usually have 3 good ones and 4th as a project / special teams standout. Gay did very well last year and he could make some noise in camp for more playing time. It will be interesting see how our secondary plays out because McFadden is in the last year of his deal and so is Townsend. The team probably won't have a problem re-signing Deshea to say a 2 yr extension to help teach the young guys and be a good veteran presence back there. McFadden though, if he doesn't step up this year he might find himself the odd man out after 2008 where Gay or a draft pick this year could step right in.
