PHOENIX – John Lynch’s draft preparation as a first-year NFL general manager prompted him to make a phone call Monday to Jim Harbaugh.

“I talked to an old 49ers coach yesterday,” Lynch said at the NFL owners meetings. “He was great. He has a lot of players who are draftable. (He) gave me a lot of great information, and it was entertaining, as it always is with Jim.

“He just said, ‘Fired up for you, man,’ then we started talking about his players. He had to go to a meeting and I had to go to a meeting, so it was quick.”

Before Lynch could quiz Harbaugh about some of the Wolverines’ draft-eligible prospects, Harbaugh had a brief chance to catch up with his brother, John, the Baltimore Ravens head coach.

“It was fun because right when we called, his brother was right there,” Lynch said.

“So John came over and before I could get on the phone, John and Jim were talking. I said, ‘Hey, you’re cutting into my time, give me the phone.’ We had a good time.”

Michigan’s top prospects are safety Jabrill Peppers, who won the Paul Hornung Award as the nation’s most-versatile player, and edge rusher Taco Charlton.

Lynch said he does not ask “lazy questions” of any college coach about his former players. Instead, he’s looking at specifics, such as what position a player is better suited to play at the NFL level.

Harbaugh, who was let go after the 49ers' 8-8 season of 2014, enters his third season at his alma mater after two seasons with 10-3 records.
