It looks like there may be a slight bit of evidence of nose wheel contact. Look just left (and above) the two yellow jacketed fellows in the foreground, just inside the left main track. That is where I would expect the nose wheel to be, if it were making a track.
It looks like the track you are pointing out is actually dual (faint) parallel tracks that likewise parallel the MG tracks (in fact they go back almost as far as MLG first impact). In that case, such tracks cannot be the NLG, but surely point out to the open (why open?) MLG doors.
As a sidenote, the MLG retract sequence in the MD-80 is MLG door unlock, then open, then MG unlock & retract, then MLG door close&lock. Is that pointing out to something? ...or maybe just the impact unlocked the MG doors?
Now that I think of it, most likely a crew LG 'up' selection, or (-manual unlock and-) loss of hydraulic pressure (due to ruptured engine pylon lines???) or mechanical door mechanism failure would also be required for MG doors to open...someone with an MD-80 manual can confirm?
