The San Francisco 49ers may only be two days into minicamp and a few weeks into the offseason program, but Torrey Smith said Wednesday that the chemistry is already building between him and his new quarterback Colin Kaepernick.

The two aren't new acquaintances; Smith said that he and Kap had trained at the same facility in past offseasons. He referenced Kaepernick's "cannon" and how it differs from the strong arm of his former Baltimore Ravens teammate Joe Flacco.

"Joe (Flacco) has a great arm, probably the strongest arm in the league, but Kap's is something different with that velocity," Smith said. "I don't know how to explain it, but it's something different."

Tuesday's minicamp practice was closed to the media, but according to Smith, Kaepernick put on a show.

"He's doing a great job," Smith said. "Ya'll aren't out there, but some of the throws he made yesterday were ridiculous."

Without divulging the exact play call, Smith went on to describe said ridiculousness.

"It was cover two and I had a conversion," Smith said. "It turned into a deep route and there was a small, a really small window for him to make the throw between (Antoine) Bethea and myself. If he put too much air on it, the ball is going to get tipped in a real game, and I'm going to get knocked out. But, he threw it where only I could get it and I didn't break stride. And it was on a rope, 35 yards on a rope. It would have been a touchdown. It was ridiculous."

Smith's account of the play is strong evidence that Kap's well-documented offseason workouts with former NFL star Kurt Warner, coupled with the instruction from San Francisco quarterbacks coach Steve Logan has been paying off.

As for Smith, the heralded free-agent signee was inked to a five-year deal earlier this offseason. The 49ers newest target hauled in a career-high 11 touchdowns in 2014 and topped 1,000 receiving yards in 2013.

He said his transition to the Bay Area has been easier than you might expect. Smith is coming from a winning tradition in Baltimore and wanted to join a franchise with a similar pedigree.

In addition to his familiarity with Kaepernick, Smith is projected to start across from his former Ravens teammate Anquan Boldin, whom Smith said "taught him how to be a pro."

The rest of the team is similarly transitioning to a new era of 49ers football under head coach Jim Tomsula, which appears to be going smoothly.

"I think everyone is bought in to what he's preaching," Smith said. "Honestly, it would be tough not to. He seems like a very player-friendly coach. He really cares about the guys and that tends to show when you have a relationship like that with the players."

Smith had similar sentiments on his new offensive coordinator Geep Chryst.

"First and foremost, he's a great teacher," Smith said. "The way they're explaining things to us and installing things is really helping us truly understand the game. I think he's doing a great job."

With a big free-agent contract comes added expectations for Smith to produce in 2015. He said he's more than ready for the task ahead.

"You've got to prove yourself all over again," Smith said. "You're getting a higher paycheck and there comes responsibility with that. I just have to prove my worth each and every day."
