'Clay, who has played four seasons in Miami, has had at least 50 receptions and over 600 receiving yards in each of the last two seasons. Bills general manager Doug Whaley mentioned at the NFL Scouting Combine that new offensive coordinator Greg Roman likes to utilize the tight end position, so Buffalo is going to have to upgrade. Clay is the type of athletic playmaker who can play the "move" role on offense and make plays out of the backfield and as an in-line tight end. That versatility will appeal to head coach Rex Ryan, who likes to use a fullback on offense.'
