Andrew Luck showered praise on Jim Harbaugh and the coach's quarterback legend grows

Jim Harbaugh's quarterback reputation is already strong and Andrew Luck backed it up.

Jim Harbaugh has his work cut out for him in dealing with an unsettled quarterback situation for the second straight year in Ann Arbor. Michigan has already dominated Hawaii with Wilton Speight under center, but it was yet another season in which the starter wasn't revealed until kick-off in the opener, and Harbaugh's quarterback reputation will be on the line again in 2016.

Kyle Meinke of MLive.com brings word from a former pupil of Harbaugh's though, and Andrew Luck backs up everything we have been led to believe about the head coach and his work with signal-callers. Luck had this to say:

"He's a heck of a coach. He's a winner. I know I learned a bunch from him and I feel like I grew as a player, as a man, a lot under him."

"It sounds cliché, but (what he really taught me was) competitive edge. How to play quarterback, not just on the field stuff, but the off the field work description, in a sense, that a quarterback has. He's a heck of a coach."

Harbaugh helped to mold Luck into the top overall pick in the 2012 NFL Draft and, obviously, he has enjoyed some success at the NFL level. While Speight (and John O'Korn, if it becomes necessary) does not possess the same physical ability as Luck, Harbaugh performed miracles with Jake Rudock in 2015 and his list of quarterback exploits also extends to Colin Kaepernick and Alex Smith.

It isn't difficult to find a former player that will praise Jim Harbaugh, but when it is a quarterback of the magnitude of Andrew Luck, it is probably worth listening.
