Since his three-touchdown explosion against Washington in Week 4, Donnell has averaged a respectable 3.6 reception, 36.8 yards, 0.4 touchdowns, and 7.48 fantasy points per contest.
If you factor out his two touchdowns, in that span, Donnell is averaging just 5.1 fantasy points per contest.
Still, Donnell is averaging 5.8 targets in his last four games, and the Tennessee Titans have allowed some big points to tight ends this year, including three touchdowns in their past two games.
