ALLEN PARK, Mich. – A week from now, the Detroit Lions will have their initial 53-man roster set and it finally will be a game-that-counts week as Detroit prepares for its season opener against Indianapolis. But from now until then? Well, there’s a lot that can happen. We touch on some of that in this week’s Lions Mailbag, filled with your questions. Have a question for a future Mailbag? Use the hashtag #LionsMailbag on Twitter, email me at michael.rothstein@espn.com or ask away on my Facebook page (which give a follow to, as well). Now, on to your questions.

We have more decent DTs than roster spots. How realistic is a trade to bypass FA for, say, a backup TE or CB on a cut list? #lionsmailbag

@mikerothstein: Bob Quinn's predecessor, Martin Mayhew, was a big fan of making trades. Quinn has shown he's willing to do it in the right scenario as well - think Jon Bostic. But at this point I'm not sure if a deal would happen because the Lions would need to find a team that needs a defensive tackle. So it'll be something to pay attention to as third preseason games take place this weekend. At this point, an injury might be what necessitates a trade for another team. I don't know if a player-for-player trade will happen, though. But figure Quinn to kick around any idea he possibly can, particularly if it can help the Lions down the road.

The optimism that accompany top drft picks seem absent with Decker & Robinson. Did Quinn miss in his first draft?

@mikerothstein: I don't think it has anything to do with that and it is way too early to judge Bob Quinn on this draft. Why you're not hearing a bunch of "optimism" or hype about either player is because of the positions they play and the roles they are in. Taylor Decker plays left tackle, one of the hardest spots for rookies to begin their careers. Decker has been improving, but growing pains will be there. As far as A'Shawn Robinson, he has improved the past couple of weeks, but he's at the deepest spot on Detroit's roster. He's not supplanting Haloti Ngata or Tyrunn Walker in the lineup, but he'll be a rotational guy. And learning how to play defensive tackle in the Lions' system is much different than what he was doing at Alabama, so there is an adjustment period. Heck, it took a veteran like Walker a while to pick it up last year. So I wouldn't read too much into that yet.

@mikerothstein #LionsMailbag does A.Boldin take passes away from TE's if Ebron not ready to go?

@mikerothstein: At this point, despite his limited practices, I still believe Eric Ebron will be ready for the opener against Indianapolis. Remember, there's little reason to push him in the preseason since the games don't count and there's no reason to risk re-injury at this point. That said, if Ebron were to be unavailable for the season opener I would imagine you would see even more Anquan Boldin - and probably TJ Jones - than a tight end on passing plays. On rushing plays, you probably would see Matthew Mulligan or Cole Wick or both. It's likely Mulligan or Wick would still be in the game in base sets, but you would have to imagine the times either one of those players would be the first or second option would be minimal. So that's a long answer for yes, Boldin would see an uptick in targets if Ebron were not to be available.

Peter from Parts Unknown asks: Do you see the Lions keeping six receivers with Quinshad Davis as the sixth [receiver] and make him run tight end routes as a receiving tight end?

Rothstein: It’s an intriguing question, but if they keep six receivers it won’t be to convert one into a tight end. Quinshad Davis is a big receiver with good size and fantastic hands. But he’s an outside receiver, so he wouldn’t be running tight end routes. Those are two different positions. That said, I don’t see the Lions keeping six receivers at this point. That number is probably at five.
