Former Super Bowl-winning quarterback Joe Theismann has never been known to run out of things to say.

He has always been quick to offer up his opinions on today's NFL and last week, he made no exception. What started off as a bizarre statement about LeBron James, opened up a huge can of worms and sparked an NFL vs. NBA debate.

Former Super Bowl-winning quarterback Joe Theismann has never been known to run out of things to say.

He has always been quick to offer up his opinions on today's NFL and last week, he made no exception. What started off as a bizarre statement about LeBron James, opened up a huge can of worms and sparked an NFL vs. NBA debate.

It all began with Theismann saying that he thinks LeBron James would be a great NFL quarterback. Receiver, tight end or defensive end, maybe. Quarterback? I'm not going to buy that one, Joe.

Everyone knows about the superior athleticism of LeBron. He's 6-foot-8, about 255, 260, has a 40-inch vertical leap and looks like he can easily run a 4.4 in the 40.

However, last time I checked, freakish athleticism doesn't equate to being a great NFL quarterback. It certainly helps; it's a tremendous bonus, but it is in no way a prerequisite.

If it was, Tom Brady surely wouldn't have won three Super Bowls. He wouldn't have even stepped foot on the field with his blazing 5.2 speed. Steve Young would have won four or five rings, and Michael Vick and Randall Cunningham would have been right on his trail.

We don't even know if LeBron can actually throw the ball. And to be quarterback, that's kind of important.

It's the toughest position to play in all of sports. You have to have the arm strength to make all of the throws, you have to be extremely accurate, you have to be able to read defenses and you have to be even tougher mentally than physically.

And being able to throw the ball accurately enough to play in the NFL, that's not something you can learn in an offseason. You're either accurate, or you're not. So, the whole LeBron at quarterback argument seems way out there.

If he had said receiver, I might have agreed. At least we know he was an all-state receiver in high school.

Even then, being an NFL receiver is about more than just size and speed. You have to be a great route-runner.

Why do you think so many 4.2 and 4.3 guys that averaged 20 yards a catch in college come into the NFL and can't get open? Why was it virtually impossible for anyone to cover a 4.6 guy like Jerry Rice? Because he ran some of the most precise routes the league has ever seen.

The NFL has the best defensive backs on the planet. If they can't keep up with your speed, they'll even things out with their physicality at the line, anticipation or their high football IQ.

These are all factors that make it unfair to unequivocally say that LeBron could leave the NBA right now and become a Pro Bowler in the NFL.

League Hall of Famer Warren Moon agreed, and he took the argument even further. He went on to say that players in the NFL are better athletes than what the NBA has to offer.

He said that, because of being so tall, basketball players are one-dimensional. Football players, on the other hand, are much more versatile and it's much easier for them to cross over to other sports .

That makes sense, but it's hard for me to totally agree with it.

Both sports are so different, and the skill-sets you have to have for each sport are so different. It's the whole apples and oranges thing.

I can confidently say that very few NFL players could play in the NBA and very few NBA players could play in the NFL. That doesn't have anything to do with their athleticism; it's all about their body-types and their lack of training in the skill-set it takes to make that transition.

Athletes from each league can hang their hats on their own special advantages.

For the most part, NBA players are taller, can jump higher and have more facets in their game they must be well-versed in, such as: playing defense, rebounding, dribbling, passing and shooting.

And for the most part, NFL players are stronger, physically tougher and faster.

It all evens itself out. Who really cares which brand of athlete is better? All that matters is that they're the best in the world at what they do, and that makes them amazing athletes regardless.
