FFToday's Take:It's unclear what exactly prompted Rivera to make this statement. McCaffrey and Stewart are two very different backs who complement each other well, which is pretty much how they have been used to this point. The Panthers would be silly to wear out an injury-prone back like Stewart or put too much on McCaffrey's plate when Stewart is around to be the hammer for this offense. Both players have a enticing matchup in Week 3 against New Orleans.
