As we get deeper into the preseason, it starts to become more clear which players should be moved up or down on your fantasy football draft board. More clarity on position battles and lingering injury concerns are a couple of the primary factors that dramatically impact a player’s fantasy value heading into the season. Let’s take a look at several players who have seen their fantasy stock drop during the 2013 NFL Preseason.

Le’Veon Bell RB | PIT

What a dagger for the Steelers and anyone reading this that had drafted him in an early draft. Bell was injured in the Steelers second pre-season game against the Washington Redskins. Now he will not require the Lisfranc surgery (which would have ended his season) but at best he will not be back until after the Steelers bye week, which is week 5. Bell can still be drafted but it has to be late, at a good value, to a team that is already deep at running back for it to make sense.

Montee Ball RB | DEN

I still feel that Ball will win the starting job for the Broncos and still will have a stellar year however, all the reports from Denver camp has been how it will be a time share between Ball and Ronnie Hillman. So you have to take this information and bump him down a little bit. Ball apparently has not fully picked up the pass blocking schemes and Denver will not keep him on the field too much if he cannot ensure Peyton Manning does not sacked a ton of times. It is disappointing but Ball has fallen outside of our top 15 running backs for this season.

Arian Foster RB | HOU

The injury concerns for Foster have slowly been mounting. A month ago he was the lock, number two overall pick but he just began to practice on August 23rd for the first time. So obviously this will make fantasy football owners a little bit nervous. Still, we believe he should not fall past the sixth overall pick in any draft. With that said, if you draft him, take Ben Tate around pick 75 just to lock up the Houston back field.

Rob Gronkowski TE | NE

Gronkowski is a difference maker when he is on the field, there is no question about that but when he will be on the field is getting less and less clear. There are rumors about him missing up to the first six weeks of the season and clearly, you need to keep that in mind when drafting him and there we have bumped him down our rankings.

LaMar Miller RB | MIA

I am just going to put it out there. At this point LaMar Miller is being grossly over drafted. The Dolphins have said that he has not locked down the starting role but for some reason Miller is still going ahead of guys like DeMarco Murray and Reggie Bush in some cases. The hype has gotten way out of control for a guy that might not start.
