The Jets’ expectation is for Chris Johnson and Chris Ivory to provide a formidable 1-2 punch to help reduce pressure on quarterback Geno Smith.
Ivory and Bilal Powell had a nearly 50-50 split in carries last season, so it’s conceivable that Johnson could see about a 35%-40% decline in carries if the Jets stick to that formula. Johnson also provides insurance if Ivory, who has durability concerns, misses time.
A 35% to 40% decline would put Johnson in the 167-181 carry range, though we'd guess that he'll get at least 190 to 210 carries in the Jets' run-heavy offense. (Bilal Powell rushed the ball 176 times in 2013.) The Jets have averaged 493.5 carries over the past two seasons, so it's conceivable that Ivory and Johnson could both reach around 200 carries, provided they both stay healthy. Assuming 240 total touches for Johnson (200 carries, 40 catches) at his 2012-2013 FP/touch rate (.609), he would score around 146 fantasy points, or RB20 numbers.
