Niagara Gazette — "That's something that's totally out of my control," Smith said, referring to the number of newcomers at his position. "What I do is focus on myself to be the best player I can be, and improve every day."
Smith is now the Bills' most experienced receiver, and adds value with his versatility, particularly on special teams.
In two seasons in Buffalo, he has a combined 37 catches for 392 yards and three touchdowns. He also scored returning a kickoff last season.
Smith's role as a wildcat quarterback, however, is no longer as attractive under Marrone as it was under former coach Chan Gailey.
Marrone, on Monday, said he wants Smith to focus on playing receiver and special teams.
Smith first showed off his versatility at Missouri, where he became the first college player to surpass 8,000 yards passing and 4,000 yards rushing.
He spent his first five NFL seasons playing in various roles with the New York Jets, who selected him in the fourth round of the 2006 draft.
Overall, he has a combined 970 yards rushing and four touchdowns; 949 yards receiving and five TDs; has thrown one touchdown pass; and scored four times returning kickoffs.
Smith credits his versatility as a key in establishing a long-term NFL career.
"I'd say I'm just tremendously blessed to be able to contribute to a team in different ways," Smith said. "If I have one role, and they move me to another role, I can do that and contribute."
