The San Francisco 49ers' defensive players have seen a different player at the start of training camp in Colin Kaepernick.

"I'm very optimistic about the season Colin will have this year," said Eric Reid.

"He's been throwing the ball very well through the offseason program," Reid said. "A couple balls, I was like, 'Man, that was a good throw.' He's definitely been putting in the work and it shows. I'm excited."

Antoine Bethea pointed out that Kaepernick -- who worked this offseason with former-MVP quarterback Kurt Warner -- is "not telegraphing where he's going," while Reid praised the quarterback for "making the touch throws on the deep throws, and the ball is hanging and dropping over the DBs."
