While Colin Kaepernick was busy this offseason shooting national and regional commercials, posing clothed and naked for magazine covers and making appearances at every celebrity gathering that had a red carpet, most NFL defensive coordinators were doing their homework on the 49ers' quarterback and San Francisco's read- option offense.
And this is what they learned: If you assign a linebacker to do nothing but "spy" Kaepernick's every move and play man-to-man coverage in the secondary, you have a good chance to slow Kaepernick.
The Green Bay Packers must have spent the summer focused on how to stop Kaepernick from running on them like Adrian Peterson.
Mission accomplished. Kaepernick rushed for only 22 yards on seven carries with Clay Matthews in his face every time he kept the ball.
But Kaepernick exploited the Packers' zone defense, throwing for a career-high 412 yards and three touchdowns in the Week 1 victory.
In back-to-back losses to Seattle and Indianapolis, Kaepernick faced man-to-man coverage. The result was a combined zero touchdowns and four interceptions.
You think Kaepernick will see zone defense the rest of the season? Yeah, me neither.
The 1-2 49ers are feeling heat like never before in San Francisco.
They made the controversial decision to play linebacker Aldon Smith two days after his arrest on suspicion of DUI, then said he would be away from the team while he seeks treatment for substance abuse.
Coach Jim Harbaugh was reportedly yelled at by Frank Gore after the running back got just three carries for 12 yards in the second half after rushing for 70 in the first two quarters.
With the offense scoring once in the past two games, the defense giving up six rushing touchdowns (seven total in 2012) on 414 yards, their best pass rusher entering a rehab facility and injuries piling high, Harbaugh may now be re-phrasing his postgame question:
"Who had it better than us?"
What to watch
Baseball, Giants vs. Dodgers, 7:15 p.m., CSNBA: Nothing's at stake, but it's still North vs. South playing baseball.
What do you think of Shaquille O'Neal becoming part owner of the Kings?
I love it.
I hate it.
I don't care.
