It is. I think the term special or great has a meaning and don't use it for backs like Murray. I don't think any one season makes anyone a "special" or "great back". Most backs are average, which doesn't mean I don't think they are good, but they are not special. Smith, Sayers, Brown, Sweetness, Sanders... those are great backs to name a few. Murray, McFadden, McCoy, etc... good backs.. etc.. There is nothing wrong with being average. And yes, obviously an average back can lead the league in rushing, as Murray did. When backs like Chris Johnson go over 2K does that make him an all time great or a back that had a really special year? I would call Chris Johnson an average back too, good not great.. had a great year once. A. Foster.. good not great,, led the league in rushing one year... not a special back either. MJD, lead the lead in rushing,, again, good not great back.. But back to the point of what I said about having no effect, if we had 29 this year and everything else stayed the same, we would still be 4-12 or even worse with his fumbles. Tony missed 2 games I believe during 29's tenure here, we lost both. And if you look at the numbers, Murray and McFadden are very much alike.
1,127 attempts, 5228 yards 4.6 average VS 1277 Attempts, 5336 Yards 4.2 average,, since 2011 (Murray's first year), one has missed 9 games due to injury and one has missed 10 games due to injury. So if one is special, they both are, if one is average, they both are. IMO.
