Last month, Patriots coach Bill Belichick couldn’t stop gushing about what a weapon fullback Marcel Reece was. The week before, Butler had a 47-yard touchdown catch. “We tried to get Kenbrell involved, so his play count was up a little bit higher,” Raiders interim coach Tony Sparano said. The Raiders have got almost nothing out of the tight end position this season, as Mychal Rivera has struggled with drops and fumbles, and has 13 catches for 101 yards.
