I was just thinking how cool it would be to have one of those "unquestioned elite" units on your defense.... IE the purple people eaters, fearsome foursome, ect.... (I don't think there are any secondaries either... Maybe I'm wrong?)
A few things that jump out at me from reading the purple people eaters wiki page is that they all have pro bowls on their resumes. Barring an upset, all of our players in our secondary should have at least 1 pro bowl. And, even though Sherman doesn't have a pro bowl, he has a 1st team all-pro on his resume now, which is much cooler than the pro bowl. Same with Earl, they are on their way to great careers.
Second, they all made the pro bowl in the same year at least once, and the majority of them three times. So far the majority of our secondary has made the pro bowl once, and they are all very young (except Browner).
Third, they have at least one HOF'er. Now, I know this is really jumping the gun, but I believe that Richard Sherman and Earl Thomas are HOF'ers, with Kam having an outside shot. These guys are straight up spectacular.
Now this whole topic is probably a little premature, but I think this unit really has the potential to go down in history as the BEST secondary in NFL history, complete with a nickname to go with it
