Was Harbaugh-to-CLE Lombardi's idea?

Since being terminated as Cleveland Browns GM, Mike Lombardi has moved on to join the New England Patriots as a special assistant to coach Bill Belichick. Per ESPNCleveland.com's Tony Grossi, CBS announcer Jim Nantz is a friend of Lombardi and told Grossi that Lombardi was the man behind the Browns' attempt to "trade" for San Francisco 49ers coach John Harbaugh.
