### Lamar Miller has produced a very solid third season, climbing to 12th in the NFL in rushing and ninth in per-carry average among running backs.
But his season has been somewhat strange in this regard: He hasn't been given as many carries as most of the other backs who rank among the league leaders. And when he is given a heavier workload, his production seems to tail off.
On his first through 10th carries, Miller has averaged a robust 5.4 yards: 134 for 718.
But on carries 11 through 20, his average drops to 2.4: 44 for 111.
That’s not typical of some of the league’s best backs. Of the players who rank in the top five in rushing, four had comparable averages on carries 1 through 10 as carries 11 through 20: Dallas’ DeMarco Murray (4.7, 4.9), Pittsburgh’s Le’Veon Bell (4.7, 4.7), Philadelphia’s LeSean McCoy (4.2, 4.3) and Baltimore’s Justin Forsett (5.6, 5.4). Seattle’s Marshawn Lynch’s average dips from 4.8 to 3.9.
So why the dropoff for Miller? “I don’t have any idea,” he said.
In each of Miami’s past three losses, Miller’s production tailed off significantly after halftime, though in the case of the past two games, lack of opportunity was a major contributing factor:
### Against Denver, he ran six times for 52 yards in the first half but just six times for seven yards in the second half.
### Against Baltimore, he had 9 carries for 47 yards before intermission, but his three second-half attempts yielded just six yards.
### Against New England last Sunday, he had 13 carries for 51 yards in the first half but lost four yards on three carries in the second half.
In Miller’s defense, he had such few carries in the second half against the Ravens and Patriots that it’s difficult to get into a rhythm. And it would be interesting to see what Miller would do if the Dolphins gave him 20 carries. (He has had just two games with more than 15 carries: 18 vs. Chicago and 16 in Sunday's Patriots game.)
The diminished production as the game wears on is surprising, partly because Miller said his weight gain from 212 to 220 last offseason made him more physical and “harder to bring down.”
That has helped in short yardage, even though he was stopped short on a third-and-three early in the second half against the Patriots.
