SANTA CLARA, Calif. -- This is what Colin Kaepernick had to say about his limited offseason work with new receiver Stevie Johnson: "It was pretty easy. He's another guy that's easy to throw to because he creates so much separation. Very quick, very deceptive, and I'm happy he's on our side of the ball."Thursday, in the 49ers' first training camp practice, we could see why Kaepernick was so pleased that the 49ers' traded a mid-round pick next year to Buffalo for Johnson.
