The struggle is real in San Francisco. can be one of the most effective quarterbacks in the NFL -- when used properly.Over the past two weeks, Kap Clayton Kershaw Jersey 's looked like a true franchise signal caller, completing 39 of 62 pa ses for 602 yards, four touchdowns and zero interceptions -- good enough for a sparkling 116.5 pa ser rating. Outside of , no other quarterback has rushed for more yards this season.But the are 2-4, . This past Sunday's snapped a four-game losing streak.So what's the problem?The are trying to put a square peg in a round hole, leading to inconsistent play at the game's most important position.The current offense doesn't maximize Kaepernick's raw athleticism and running ability, which has proven to be wildly succe sful in the past (especially under Jim Harbaugh). Combine that with the reality that Kaepernick developed the majority of his high-level playing skills in an offense that has limitations when it comes to quarterback development, and we have a real problem in San Francisco Sandy Koufax Jersey .In 2011, when San Francisco traded up nine spots to draft Kaepernick 36th overall -- the fourth pick in the second round -- Harbaugh had a master plan. Most teams build offenses around the quarterback; you see it in New England with and in Green Bay with . But with Kaepernick, Harbaugh built the offense around the running game. During the 2012 season, the had , rushed for the 1,214 yards, and offensive linemen and both made the .

So before the ball is snapped, the best QBs already have ruled out certain options. This skill is not inherited -- it is learned. Unfortunately, Kaepernick doesn't have that training.As a star college quarterback at Nevada, Kaepernick played under head coach Chris Ault, the man who created the pistol offense. Running this scheme to near Mike Piazza Jersey perfection, Kaepernick accumulated 14,210 total yards (10,098 pa sing, 4,112 rushing) as a four-year starter. Mind-boggling numbers, for sure, but Kaepernick was never asked to diagnose sophisticated defenses or go through progre sions to find the open receiver. In the pistol formation, the quarterback lines up about 4 yards behind center, closer than the typical set in a Russell Martin Jersey traditional shotgun formation. The shortened distance makes it easier for the quarterback to read the defense at the line of scrimmage, but also limits the amount of time he has to go through pa sing options. In most situations, the quarterback is asked to read high/low/run. So his progre sions are: 1) throw the deep route; 2) throw the short route; or 3) run the ball. This explains why Kaepernick has lost his dynamism in a more traditional NFL offense. Six games into his fifth NFL season, Kap continues to struggle with surveying and di secting complicated pro defenses.When the awarded Kaepernick with , it came with an unwritten predicament:Do they focus on short-term succe s or strategize for long-term utilization?This is the dilemma GM Trent Baalke and head coach Jim Tomsula face in regard to using their franchise quarterback today.

Not surprisingly, San Francisco has gone 1-5 in those games.Will we see vintage Kaepernick, building on his current two-game roll? Or ineffective Kaepernick, trying to be something he's not?
