Quarterbacks get booed all the time, but few are so bad that their home fans start to chant the backup quarterback’s name, especially when his name is David Carr. This matters little to Alex Smith now after he was re-signed by the 49ers last night to a reported one-year contract worth $5 million.

It’s been five long and disappointing seasons since San Francisco had the misfortune of holding the first overall pick in a weak 2005 draft, forcing management to bring Alex Smith and his misery into their huddle. While Smith’s clear purpose in this short-term contract is to keep a seat nice and toasty for second-round pick Colin Kaepernick, this deal still wreaks of a franchise that’s unwilling to admit a mistake, and is still trying to justify and salvage a failed first overall pick.

Over his five seasons in the Bay Area, Smith has had only one year in which he started all 16 games, a blatant sign of drafting failure. Eight other quarterbacks (Tim Rattay, Ken Dorsey, Cody Pickett, Trent Dilfer, Shaun Hill, Chris Weinke, J.T. O’Sullivan, and Troy Smith) have started a combined 45 games during Smith’s troubled tenure. Some of those starts were due to injuries, but most were because of overall terribleness. Smith has more career interceptions (53) than touchdowns (51), and still hasn’t eclipsed the 3,000 yard mark for passing in a season.

Yet somehow Smith still finds a way to stick around. Sadly, in an awful NFC West that will likely continue to be awful, anyone has a shot, and after a locked out offseason Kaepernick needs time to mature and develop. Smith is a fine candidate to take his body shots while Kaepernick observes from afar, and the money is reasonable.

It just won’t be pretty.
