I agree that he's a player who means more to his NFL team than to his fantasy team, however I look for him to improve. First of all the Redskins offensive situation was less than ideal last year. Brunell was the starter for nine games and was ineffective, followed by Campbell who was making his first pro starts without the benefit of reps with the first team. Portis was injured for most of the year. Moss, too, had injury problems. Saunders took most of the year to figure out that power running and play-action are a formula for success with this team. These things figure to all be improved this year.
The other thing to me that's intriguing is that Brandon Lloyd's attitude problems did not impress Gibbs and the rest of the staff at all. Randle-El may actually end up as the second WR for much of the time. No, there's been no official announcement or anything, but there's no doubt that the team loves ARE and his spirit and leadership.
Finally, if you're in a league like I am that awards bonuses for big plays, the fact that ARE is the primary dealer of gadget plays for the team can only help. Those plays, e.g. the WR reverse option pass, have as much of a chance as any to go for long yardage and scores, which along with his PR duties adds bonus value to him.
Last year in my PPR league the 48th ranked WR (the last WR theoretically to start in a 16-team, start-three WR league) was Matt Jones, who had 41/643/4. I believe that ARE can put up those numbers or better for Washington and can be a borderline starter.
