You can question Jim Harbaugh's choice of clothing and media relations all you want, but the one thing he shouldn't be questioned on is quarterbacking. For someone that's spent a combined 30+ years playing the position at all levels and grooming young men to play it on a professional level, Harbaugh's quarterback whispering speaks for itself.
He turned a no-name like Josh Johnson at the University of San Diego (pictured above) into an NFL draft pick. He groomed Andrew Luck into a top NFL prospect and #1 overall pick in last year's draft. He also resurrected the fledgling career of Alex Smith. And now he's turned Colin Kaepernick into one of the most dangerous dual-threat quarterbacks in the NFL.
Basically, Jim Harbaugh can mold NFL quarterbacks out of dirt, so who are we to second guess him when it comes to having a reliable backup to Kaepernick? Nobody's seen soon-to-be backup Scott Tolzien play a single down of regular season football, but with Harbaugh's impeccable record of developing NFL quarterbacks, we have no reason to doubt that Tolzien would be ready if needed and called upon.
