I don't see Revis playing here or SF. I like Browner out there anyways. There are folks who think he isn't a great cover guy, but he holds his own well when he doesn't flat take his guy out of the play.
I see Revis as an improvement for SF for sure, but I think the SF secondary is better than they looked at the end because if the DLine play dropping off without JSmith being 100%. The Hawks just blasted that line for the most part without him and Rodgers/Brown/Culliver were being asked to cover too long. Those guys are much better with a good pass rush and I would think Baalke and Hardouche want to invest their money there if they can.
Wonder what that Smith trade will warrant... Possible they use that chip to address their DLine OR secondary.
