No reason was given for the move, but players who have been placed on NFI prior to the start of camp in year’s past have often found themselves there because they have failed the conditioning test and/or their physical.
Update: Ben Volin reported that Blount ended up on the NFI after failing his conditioning test.
This is probably nothing to worry about, but we'll monitor the situation throughout camp. It’s always dicey to buy into the New England running game, but Blount has been good while toting the ball for the Patriots. Since 2013, he has averaged 11.3 touches for 57 yards and 0.65 TD in 26 games. Those are solid RB2 numbers in standard (low-end RB2 in PPR). However, in his last 15 games with the Patriots (including the postseason), he has turned 14.2 touches into 73 yards and 1.0 TD; those are strong and low-end RB1 numbers in standard and PPR formats, respectively. Granted, he tends to score his points in bunches -- e.g. 30 carries, 148 yards and three touchdowns against the Colts in January -- but he’s been getting pretty consistent run since December of 2013, registering at least 10 carries in 11 of his last 15 games with the Patriots. Given his 6th round ADP, he should be a fine target as a RB3, or as a RB2 for the “wait on RB” crowd. For more on Blount, check out this article by Sr. Editor John Paulsen.
