Tim Tebow has work to do if he’s going to win over New York sports fans. The new backup quarterback for the Jets was booed at Yankee Stadium on Sunday night when he was shown on the giant video board, even though he was wearing a Yankees cap. Tebow cracked a smile and acknowledged the camera. There was a smattering of cheers, but most of the initial reactions were boos. Tebow was acquired by the New York Jets from Denver last month. He is expected to back up starter Mark Sanchez, even though Tebow rallied the Broncos to the NFL playoffs last season and became a polarizing sensation in the process. – AP
