CLEMSON — Clemson quarterback Deshaun Watson isn’t worried about his Heisman Trophy status or looking for the longball, not with the 11th-ranked Tigers off to a perfect start. Many were expecting Watson to put on a show for a national audience last Thursday night in Clemson’s 20-17 victory over Louisville. Instead, he was steady and unspectacular — and probably didn’t wow many Heisman voters still figuring out contenders from pretenders.
