‘Lots of bodies but not a lot of answers. That’s how the Bills will enter the season at tight end, a position they talk about improving each year but never seem to seriously address. This year’s picture is clouded even more by the fact Robert Royal, the incumbent starter, is coming off right knee surgery. The team is counting on Royal returning to full health, but he may not be able to go fully until July training camp. Meanwhile, his absence is giving more repetitions to Derek Schouman, Tim Massaquoi, rookie Derek Fine and free agents Courtney Anderson and Teyo Johnson.’
