One player scored 29 touchdowns and threw just 9 interceptions in two seasons, took over a 1-4 losing team and made the playoffs, and led his team to an unexpected playoff victory over the Pittsburgh Steelers in overtime. He never got a serious chance to play again.

Some blame it on him taking a knee on the field.

Another player scored 85 touchdowns with 30 interceptions over his six-year career and led his team to a Super Bowl. In his last season, he threw four times more touchdowns than interceptions. Yet, no one has given him another chance.

Some blame it on him taking a knee on the field.

But in both cases, some people are wrong. Neither Tim Tebow (the first player) nor Colin Kaepernick (the second player) lost their chances exclusively because of their activism. And the fact that Tebow faced the same fate proves Kaepernick isn't being discriminated against for his race, as many have alleged.

Their on-field similarities are actually more important than their off-field activism.

Tebow's fame and his faith, including kneeling on the field to pray, were seen as a distraction, no matter how absurd that sounds. Kaepernick's decision to protest a legitimate issue using disrespectful and demeaning tactics (kneeling during the National Anthem) alienated more people away from the cause he supports, creating a major public relations dilemma for whoever would hire him.

Kneeling, however, wasn't their demise. It was the fact they are both running, dual-threat quarterbacks; in many ways, their running abilities propelled their entire offensive approach. Just like Robert Griffin III, an NFL team would need to design a specific and separate set of offensive plays to fit this style. It's a model often used in college, but NFL teams have systematically abandoned this type of offense.

So why don't RGIII, Kaepernick, and Tebow have jobs in the NFL? It's because no NFL team is going to design a separate offense for their backup quarterback. In order for any of these three to have a chance at a job, they would need to be starters, and on top of that, the team would likely need to have another running quarterback as a backup in order to not have to create two offenses.

One anonymous league executive told Sports Illustrated about Kaepernick, "To me, the protests, all that, it wasn't even a factor for us. It was the ability to fit within our offense. He doesn't throw the ball great, he's more of an on-the-move, zone-read type of quarterback. He needs to be in a specific system."

As has been widely-covered and statistically-proven, the NFL is becoming more pass-heavy every year. The reason is simple and similar to the popularity of the three-point shot in basketball. NFL teams pass more because it moves the ball faster and they score quicker. If teams have running quarterbacks, that means fewer passing plays.

And if you look at the stats for these three quarterbacks, you will see their total yards produced don't compare to even a mediocre passing quarterback. In Tebow's best year, he averages 170 yards of running/passing production per game, Kaepernick's best year was 250 yards per game, and RGIII's best was 283 yards (his last year with the Redskins, he averaged 210 yards per game). Ryan Tannehill, who is a below-average throwing quarterback, averaged more than 271 yards per game in his best year.

Running quarterbacks are going extinct in the NFL. Certainly, distractions don't help anyone trying to get a backup job, but, by far, the biggest reason Kaepernick doesn't have an offer is his style of play.
