While Colin Kaepernick's offseason work with Kurt Warner and quarterback guru Dennis Gile have received rave reviews in some quarters, at least one entity remains unconvinced of the quarterback's new leaf.

NFL.com's fantasy football report indicates that it believes the San Francisco 49ers signal-caller will not become a top-10 fantasy football quarterback in 2015.

Colin Kaepernick rated the 21st best starter in the NFL?

"The first smartphone I ever bought had all sorts of bells, whistles, lights and pretty colors," NFL.com Fantasy editor Marcus Grant writes. "As a phone, it stunk -- which sort of defeated the purpose. Similarly, we spend so much time focused on Kaepernick's speed and ability to make plays with his legs that we sometimes ignore the fact that he struggles when delivering the football. However, it became painfully apparent when watching Kap's work on film that his accuracy was lacking. While Kaepernick completed 60.5 percent of his passes (second-highest percentage of his career), it still ranked him a disappointing 24th among NFL quarterbacks."

Grant goes on to point out the questionable decision-making and the lack of touch on Kaepernick's passes from his first three years as a starting quarterback that have led to his drop-off, not only in terms of fantasy football but also in real football terms as well.

"Improving accuracy is going to be crucial to any attempts to rebound into the top 10 for Kaepernick," Grant states. "The good news is that he's enlisted the services of former Super Bowl winner Kurt Warner (among others) to help him get better in multiple aspects of the game. One of those aspects will have to be his in-game management and making smart choices with the football. In the latest NFL Fantasy LIVE podcast, I suggested that new 49ers head coach Jim Tomsula and offensive coordinator Geep Chryst sit Kaepernick down "A Clockwork Orange"-style and force him to watch videos of Russell Wilson. Kap might have greater physical tools than Wilson, but the Seattle quarterback's on-field smarts have made him the superior player over the past couple of seasons."

Kurt Warner wants Colin Kaepernick to play like Russell Wilson

Ironically, Warner himself appeared on a San Francisco radio station a day earlier and made similar comments about urging Kaepernick to emulate Wilson.

But with a questionable offensive line, a new coaching staff and new weapons surrounding Kaepernick, the fantasy verdict is: "There are far too many unknowns surrounding the makeup of the Niners offense and Kaepernick's development to believe he'll remain much more than a QB2 in 2015."
