49ers vs. Bills: Colin Kaepernick forcing Buffalo to account for him

After his terrific performance against the New York Jets last Sunday, San Francisco 49ers backup quarterback Colin Kaepernick is forcing his opponents' hands in having to prepare for him, according to CSN Bay Area's Matt Maiocco.

The 49ers host the Buffalo Bills this week at Candlestick, and head coach Chan Gailey is getting ready for Kaepernick and the dangerous option plays he will likely run:

"[The option] puts a lot of stress on your defense to prepare for that week-in and week-out. [Kaepernick's] done a good job with running what they've put in and they've done a good job of keeping it varied, so it's not the same all the time."

Kaepernick is one of the more unheralded offensive threats the 49ers have, though that may be changing. He set an NCAA record with at least 2,000 passing yards and 1,000 rushing yards in three consecutive seasons for the Nevada Wolf Pack, and has a large, elusive frame while on the move. He's got a cannon of an arm, and should keep the Bills guessing all day long on Sunday if he sees time.

Kaepernick rushed five times for 50 yards, including a touchdown. He threw a deep incomplete pass on his only attempt.
