Bernard has clearly been trending down in some respects.
Bernard's game log
http://espn.go.com/nfl/player/gamelog/_/id/15826/giovani-bernard
RUSHING
First five games, he had less than 13 carries once.
69 carries/5 games = nearly 14 per game
377 rushing yards/5 games = 75+ per game
1 rushing TD/5 games = .4 per game
In the two plus months since 10/11 (week 5), Bernard has more than 10 carries once.
In that span, 57 carries/8 games = approx. 7 per game
270 rushing yards/8 games = not quite 34 per game
1 rushing TD/8 games = .25 per game
Rushing production about half across the board (last 8 games relative to the first 5 games)
RECEIVING
First five games, less than 3 receptions once
17 receptions/5 games = nearly 3.5 per game
96 receiving yards/5 games = 19+ per game
0 receiving TDs/5 games
In the next 8 games since week 5, Bernard has had less than 3 receptions five times.
23 receptions/8 games = nearly 3 per game
317 receiving yards/8 games = nearly 40 per game
0 receiving TDs/8 games
I'm generally not a fan of subtracting best plays/games. That said, for the record, he had a career high 8-128 receiving in the 34-31 loss to the Cards.
So, in the other seven games since week 5, his amended receiving totals would look like:
15-189-0
closer to 2 receptions and 27 yards per game
* Based on the last two months of the season, Bernard has averaged on a per game basis approx:
34 rushing yards, 40 receiving yards (74 combined), .25 TD and about 3 receptions for PPR purposes
And to recap, relative to the first five weeks:
75 rushing yards, 19 receiving yards (94 combined), .4 TD and about 3.5 receptions per game
