Every week during the Lions season we’ll do a Twitter mailbag. Use the social media site to send your questions to Lions beat writer Dave Birkett at @davebirkett.

Q. How do you see Abdullah doing this season? Do you think he can reach 1,000 yards rushing? - @Codyxhighroller

A. Ameer Abdullah’s ability has never been much of a question. The concerns about him heading into this season are mostly about his health. If Abdullah stays healthy – he missed 14 games with a foot injury last year – I think he’ll have a really nice season. He’s quick, he’s explosive, he’s a better inside runner than people give him credit for, and given the rest of the Lions’ backfield, he won’t lack for opportunity.

Now, does that mean Abdullah will rush for 1,000 yards? He’s certainly capable, but I’m not sure the volume will be quite there for that. The Lions don’t strike me as a team that’s willing to give anyone 20 carries a game. I see Abdullah closer to 850 yards rushing with another 350 or so receiving. That’s 1,200 yards total and a pretty good season.

Q. What rookie besides Golladay and Davis make an impact - @CHEN313

A. Jarrad Davis should have the biggest impact among the Lions’ 10 rookies, but he’s far from the only one who’ll see the field. Davis will start at middle linebacker and play in every sub package, and I think he’ll be joined before long by Jalen Reeves-Maybin in the starting lineup. Reeves-Maybin is the No. 4 linebacker for now, and at a minimum he should be an impact player on special teams.

I’m not sure wide receiver Kenny Golladay will have as big a role as some expect. He’s the No. 4 receiver for now, and he plays a position that has historically been tough for rookies to have a big impact. I’d peg him at 30-35 catches for the season.

One other player to watch: Fifth-round pick Jamal Agnew could handle punt-return duties this fall. He was the Lions’ best return man in the preseason, and is certainly capable of making a few impact plays.

Q. Do you think the Lions should explore moving Robinson to left guard once Decker returns? Can't be worse then what Glasgow or Dahl did so far – @mayerpeter47

A. Greg Robinson will start at left tackle for at least the first six games of the regular season, though Taylor Decker (shoulder) could be out longer than that. Robinson has exceeded my expectations so far, and you might recall Hall of Famer Jackie Slater predicting that he has Pro Bowls in his future.

It’s far too early, though, to speculate on what happens to Robinson once Decker returns. A lot will depend on his play – Corey Robinson is waiting in the wings if he struggles – and the play of Graham Glasgow inside. I have a hard time seeing the Lions move Greg Robinson to guard once Decker returns. Robinson has not taken any snaps at the position, and the Lions consider him a tackle. The more likely scenario is that Robinson, if he plays well, simply takes over as the Lions’ swing tackle.

Q. why is the media so negative - @michael00544442

A. Jim? Is that you? I thought you weren’t on Twitter.
