Re: Lebron v Jordan, I disagree. To my mind, Lebron v Jordan only seems closer because it's a different sport. They both play offense and defense, they both score, assist, rebound, dribble, shoot, block, steal etc.
Football is different. The jobs are streamlined and very specialised. Imagine if Brady had to enter a competition where he went against Rice, Brown and LT where they all had to play QB, RB, wide receiver, tight end, OT, linebacker, DT, safety, corner, special teams etc. Brady would probably come bottom of every category except QB. So it's a different sport, it's not like basketball where direct comparisons are easier
