Murray did run for 1845 yards last year, and only just turned 27. It's not crazy IMO, especially when your passing game has question marks.
His 392 carries is the most since Larry Johnson in 2006 (416 carries).
Leading the league in carries fucking kills a running back. Here is how a player performs the following year after leading the lead in rushing attempts since 2002:

Essentially, 1 of 2 things happens to RB's that lead the NFL in rushing attempts.
1.)
Injury the following year. Since 2002, 7 of 12 years (58%) an injury has occurred and the RB has lost significant snaps.
2.)
Significant drop off. Since 2002, 6 of the 12 years (50%) have seen RB's lose significant production (.8 YPC or greater) the following year. 4 of those players (33%) lost greater than 1.2 YPC, essentially falling off a cliff.
In fact, in these 12 years, only 1 example - Michael Turner in 2010 - remains an outlier. Even still, he had an injury marred season sandwiched between the two years he lead the league in rushing, and his production had dropped so much by 2012, that he was out of the league the next year.
(You could also rightly point at Clinton Portis, although his 325 carries pale in comparison to nearly everyone else on the list. After rushing for 342 attempts the following season, his career was basically over).
Those 392 carries will have an impact on Murray. If history is any indication, at best he'll be able to string together one more solid year before falling off a cliff. At worst, his statistics will plummet or he'll run out the clock with a few more injury marred seasons. The Eagles may have traded in their used car with McCoy, but the car they got in it's place has just as much tread worn off those tires.
