I can't find the video online anymore it's been taken off do you have a link to it? I want to rewatch the run, before answering some of your points.
It's still there, but if you don't have a DVR copy or a torrent file, it's not quite easy to see.
Let me go back to the original position of the players, especially the linemen.
That will give a different perspective.
The ball was on the hash marks of the 49yd line.
The Center's feet were on the 48yd line.
He was between the hash marks, but very slightly to the outside;
his behind protrudind back close to the 47yd line.
On his right were the RG, the RT, and the TE, naturally.
Now go back to the still frames on page 3 of this thread at look at the third picture.
MJD ran up to the line and would have bumped into the Center b.u.t.t (had he stayed still) before he made the cut to the outside.
Where there were 3 Jags on the outside of the Center now is a huge hole.
Deljuan was pushed back and cleared to the inside by the double team of the RT & RG.
That wasn't so strange.
But Bulman suffered the same fate (only worse) at the hand of the TE.
He ended up 3 yards behind the LOS, just inside the hash marks.
If both of these guys can do a better job; especially Bulman, just holding off the TE at the LOS; MJD would have no room to run.
If he goes to the inside, he would be blasted by Cushing.
If he cuts outside, it would be right ino the waiting arms of Bennett.
I had mentioned that Bennett (at his deepest and most outside position) was right behind the original position of the TE.
Either way, it would have been a loss of yardage.
