Well, it turns out taking an elite receiving tight end and stranding him in a power-running WR wasteland is just disappointing for everyone involved.
Graham has scored in two games this season, but in the other two games, he's scored less than three. He put up only 29 yards receiving against Detroit, and 11 against the Packers. This week, he has a matchup against Cincinnati, and it's been almost a calendar year since the Bengals have given up a touchdown to a tight end (Week 7 of 2014).
I'm not optimistic - although you probably knew that already considering you're reading a "busts" column. Tight end is thinner than ever, so it may be tough to bench him - but if you have a backup plan, you may want to keep Graham on the bench in Week 5.
