I agree that JuJo didn't have the hole/lane that was supposed to be there on that 4th and short play. LD didn't create the hole like he was supposed to. But, that is exactly the MAIN difference between him and MBIII. On that play JuJo simply put his head DOWN and run toward where the hole was SUPPOSED to be and altimately run right into LD's big rear end. On the other hand, on that 3rd and short play with MBIII, he started to go where he expected the hole to be and kept his head UP and when the lane wasn't there he made a cut and gained 17 yards.
I'm not one of those who want to see MBIII start over JuJo, frankley i don't give a rats *** who starts, in fact i love seeing MBIII in the 4th quarter wearing down and punishing defenders. But, on short yardage running plays, i want to see MBIII in the game, he simply has better vision, strength, and determination to pick up the first down more times than not.
