Petty and Winston, as well as noted quarterback coach George Whitfield Jr., were in Ann Arbor from Sunday to Tuesday finishing up combine preparations. Part of their time was spent meeting with Harbaugh, and the video showed Harbaugh coaching them on the interview process they will go through at the combine.
In addition, each quarterback was asked about Harbaugh.
"It was a blessing to meet a guy like that," Winston said. "It was just an honor to meet him, and all of his accomplishments and the type of coach that he is.
"I wish I could have played for him."
Petty and Winston also were shown gushing over Michigan's indoor practice facility.
"This is definitely, by far, one of the best I've seen," Petty said.
Winston was more effusive: "These guys don't know how blessed they are to have this type of facility. ... I love Florida State -- you know, 'Go 'Noles' until the day I die -- but they are so much (more) advanced than us."
