Lebron James in the nfl.

What if Lebron James were to choose to go to nfl instead of going to the Nba. Everybody has seen the recent commercial of Lebron getting drafted by the cleveland browns. After he wakes up he finds out it was dream but it leaves you saying Damn!!! what if. 6'8 with explosiveness great speed and quickness, those are things unheard of in the nba. Ive never heard of a 6'8 tight end or receiver with his dominating athleticism. He could have possibly been the best player in nfl history. Greatness, The possibilties would be crazy. Many players have been two sport athletes, Deion Sanders, Micheal jordan, Bo jackson, Lebron james? I have seen film of him playing basketball in high school. His talent was obvious.But how would you feel covering him? Knowing that the guy lined up across from is probably going to run by you and if you do keep up with him he will moss you, because he is 6'8. This will probably never happen , but i wonder how does it feel to be that raw and know that you can do whatever you want to do in any sport you want to play. Greatness.
