Hmm...Let's see...
It's 4th & 1, late in the 4th quarter during the divisional playoff round game at the Rams. The play obviously goes to Zeke, handing him the ball, putting the game/playoffs on the line in his hands and letting him convert that 4th & 1 for a 1st down which would have allowed the Cowboys to keep possession and get a score to potentially tie the game or take the lead.
There were 2 ways Zeke could have ran with the ball:
1) Run between the C and LG to get that 1 yard needed for a 1st down. There was a hole there for a split second or two.
or
2) Dive over the pile between C and RG. There was a crevice that opened up above the falling RG Zack Martin. Emmitt used to dive over such falling piles and easily convert short yardage attempts for 1st downs. Even other RB Greats like Walter Payton, Marcus Allen, LaDainian Tomlinson and a few others were known for diving over short yardage piles in order to get a 1st down or a TD.
But not Zeke. Instead, he went straight into the pile, timidly, and got stuffed for a loss.
Zeke is good at hurdling DBs 1-on-1 in the open field, but he has yet to ever dive over a pile at the line of scrimmage to convert a short yardage gain needed for a 1st down or a TD. That's what separates the greats from good RBs, especially when the game/playoffs is on the line.
