Trying not to cherry pick numbers here:
Last 8 games: 102 carries, 580 yards, 5.69 YPC, 5 TDs
Last 16 games: 155 carries, 852 yards, 5.50 YPC, 6 TDs
Last 16 games with 10+ carries: 225 carries, 1,169 yards, 5.20 YPC, 9 TDs.
Doesn't turn 25 until December and the Saints didn't pick up his 5th year option for next year at $5 million, so he is an unrestricted free agent. The franchise number for an RB in 2014 was $9.5 million. He's almost a full year younger than Andre Ellington. How many guys would you rather have in dynasty right now?
		
		
	 
It will be interesting to see what happens with Ingram. It certainly wasn't a mistake to not pick up the option. $5M would have made Ingram the 10th highest paid RB in the league. You can't pay that kind of money for a RB who offers little in the passing game, which is today's NFL.  I would be shocked if he got more than $5M/year in free agency.
New Orleans is in cap hell so they almost certainly won't retain his services, unless the market bottoms out and he returns for $3-4M/year. That's very possible ... look at the RB free agent signings and extensions from the last two years.  Chris Johnson, Joique Bell, Reggie Bush, Darren Sproles, Steven Jackson, Toby Gerhardt.. those are all guys that at one point in time ran as hard as Ingram and every one offers more in the passing game. Yet none of them got over $4M per year.
