Per Trent Baalke, Harbaugh's talent evaluation with quarterbacks has been lights out, and "spot on" over the years. This is exciting to know, because it further brings faith to us fans that we can build this team into a Super Bowl team. All we've needed is a competent coach, a QB, and the other little pieces in between.
Here's an excerpt from a recent article, talking about Harbaugh's QB evaluation ability:
(Baalke speaking): ". . . I've had a chance to watch him interact at practices with the quarterback and he's just got it. I don't think you can teach it. Some guys just have it. . . . He developed one, Josh Johnson, down in San Diego. Obviously, he has a great one (Andrew Luck) at Stanford." The 49ers learned of pre-draft reports Harbaugh wrote while with the Raiders in 2002 and '03. His reports were "spot on," according to a source. Harbaugh placed a second-round grade on Tony Romo, who went undrafted. He had a higher grade on Jaguars fourth-round draft pick David Garrard, who has been a solid NFL starter the past four seasons. Harbaugh did not have a good grade on Joey Harrington, the third overall pick of the Lions in 2002.
