ANN ARBOR, Mich. (AP) -Charles Woodson says ``it's hard to watch'' Michigan play football.

The Green Bay Packers cornerback says he's even getting flak from a current teammate who played for the Cincinnati Bearcats.

``Can you believe that?'' Woodson asked reporters Tuesday during a visit to Ann Arbor.

Woodson won the Heisman Trophy and led the Wolverines to the national championship in 1997.

Michigan (5-4) has lost four straight Big Ten games and could turn a 4-0 start into a 5-7 flop a year after college football's winningest program lost a school-record nine games last year in Rich Rodriguez's debut season.

Woodson says he and former teammate Marcus Ray exchange messages about the once-proud program.

``I won't share the texts with you,'' he said.
