Veteran guard Kraig Urbik found himself in a tight-end position as the Buffalo Bills lined up for a live goal-line play in Sunday’s practice. The offense was short on healthy tight ends, and Urbik was pressed into unfamiliar duty. “They told me to run a corner route,” Urbik said. “I didn’t know what that was, but I was wide open. They didn’t see it coming.” The 328-pound Urbik made a sure-handed catch in the end zone on a pass from EJ Manuel and then delightedly executed a spike of the football. The spike left a little to be desired, but the play punctuated a successful session for the offense before a throng of more than 2,000 at St. John Fisher College. The Bills scored touchdowns on 5 of 8 full-tackling plays run from the 1- or 2-yard lines. The Bills were not good enough on goal-to-go situations last season, ranking 29th in the NFL in touchdown percentage. Sunday’s practice was the first chance to set a new tone for this season. “In order for us to win games, it’s huge for us to put seven on the board instead of three,” said fullback Frank Summers. “So it’s a point of emphasis for us.” “There was the Cincinnati game last year on the goal line where we weren’t successful,” said Urbik, referring to a game the Bills lost in overtime, 27-24. “But there were other games that we were successful. It’s an attitude when you get down on the goal line. You’ve got to be tougher than them. You’ve got to drive them into the end zone. We’ve got to do a better job of that.”
