I think that is a good strategy. Other than the WAS game that is a string of nice matchups. The NFC West gets the AFC East this year, which means not only do you get SF twice and STL twice, you also get Miami, Buffalo, and the Jets. I would rather spend $2 on Seattle but if they go higher, it is a good fall-back.
Adrian Wilson is one of the better safeties in the league. They were able to keep LB Karlos Dansby for a year, so he should still be a solid LB and still hungry for a contract. They have some talent at DE, and Chike Okefor should be back from injury. They spent their first rounder on Cromartie's cousin at CB, instead of getting Mendenhall to replace Edge.
It's hard to trust them for a year, but it's a decent gamble to start the year hot, especially for home games.
