C.J. Spiller - RB, New Orleans Saints
He wasn't doing anything special before he ripped off the 80-yard touchdown in overtime, but that showed his big-play ability, which is why owners wanted him on draft day.
You aren't going to get a ton of volume out of the guy, at least not yet, but he's so talented in open space that he can rip off huge game-breaking plays at any moment. With Drew Brees back, and Spiller healthy again, his fantasy football stock is rising with plenty of room to continue growing.
Charles Clay - TE, Buffalo Bills
He looked great in an exploitable matchup against the Giants where he was easily Tyrod Taylor's favorite target, turning in nine receptions for 111 yards on a whopping 13 targets. His day could have been even bigger as he also had a long touchdown called back on a penalty.
Sammy Watkins and Lesean McCoy won't be out every week, but Charles Clay showed that he is very talented - and this game may be what makes Tyrod realize he's got a great hot read weapon in Clay. He should continue to get passing targets, and his fantasy football stock should continue to rise, especially at the thin tight end position.
