8 rushes for a combined 5 yards and 2 TDs. So he averaged .6 yards per carry.
I think I could score 2 out of 8 times from the 1 yard line.
This is a bogus comparison.
Clearly if every one of his rushing attempts started at the 1 yard line, his total yardage couldn't exceed his number of TDs.
You also forgot that he caught a 4-yard pass for a TD also.
A.

B.

C.

D.
http://www.pro-football-reference.com/boxscores/198511170dal.htm1 yard run (no TD). Dent had a 1-yard interception return for a TD that game (44-0 blowout).
E.
http://www.pro-football-reference.com/boxscores/198511240chi.htm1 yard run (TD).
F.

In later years, he only gained negative yardage.
More usefully, he also was a blocking back on similar goalline-unit plays, with Payton scoring (rojo would get stream-rolled). Perry's time in the 40 (yards I take it) was 5.05s (OK, maybe rojo wins there).
