You are right about Archuletta, besides not fitting our new system we shouldn't sign him because he sucks. Here was my take from another thread....
Adam Archuletta=Coy Wire, just injured more. We cut Milloy because he doesn't fit Jauron's cover 2 scheme and needs to play close to the line of scrimage to really be effective; Archuletta needs to do the same. He's not a good fit here and really, really sucks in coverage: ask any Rams fan and they will tell you the same. I don't know why everyone is so eager to get all these Rams cast offs...I'll take Pickett at the right price (not 20mil) but all the others...no thanks.
You are also right about they type of DTs we are looking for, however Pickett and R. Bernard are 2 that do fit our new system. Man I hope we make a serious run at Bernard.
