I clearly saw numerous occasion last year where DMC was swallowed whole by short yardage situations...My eyes are 20/20.
It's not your eyes that you're depending on here -- it's your memory. Here are all of McFadden's short-yardage runs in 2015.

Short-Yardage Conversion Percentage, 2015
McFadden's runs 13 of 17 (76.5%)
all passes 6 of 13 (46.2%)
The stats can only tell part of the story, not all of it and not the important parts. For example if it is 4th and 1 and we are trying to run the clock out to win the game, and the RB gets the first down, that is just one time in stats, but it is a very important run in that game and in getting a win. Stats don't factor in game situations, play calling, errors made etc.

Short-Yardage Conversion Percentage, 2014
Murray's runs 19 of 26 (73.1%)
all passes 13 of 18 (72.2%)
The big missing factor when looking at these short-yardage runs is the performance of the passing game both seasons. In 2015, defenses knew Dallas was having trouble converting by the pass and that the Cowboys ran in these situations 75% of the time when Weeden and Cassel were playing (NFL average was 55% run). Defenses could guess run, usually be right, and seldom suffer when they were wrong.
In 2014, we ran 63% of the time, compared to the league average of 57%, so defenses had to play us honest. And we were equally as successful passing as running in short yardage. Any defender who guessed pass and was wrong was at the mercy of one of the league's top run offenses. Any defender who guessed run and was wrong was at the mercy of the league's leading passer.
Same situation as when we were inside the 5-yard line, where the gap between the two passing games grows even wider.
