I don't think this is the same ol' Cards. JJ Watt & Chandler Jones will be a handful. Budda Baker is still bringing it. And DeAndre Hopkins and Green? I think it's going to come down to how we play Kyler Murray. If get to him early, I think it will affect him later. We will find out about his maturation.
The other factor other teams haven't learned yet (and I think catches them off guard) is Rams now have a home field advantage. If they don't prepare for it, it will cost them (see Bucs false start penalties)
