Check here for a full list of Detroit's's roster moves.
Biggest surprise: Veteran cornerbacks Dre Bly and Eric King were among six cornerbacks released. The Lions' secondary was hardly exemplary during the preseason, but you figured Bly or King would make the team to provide some level of veteran presence. As it stands now, the Lions' cornerbacks include starters Chris Houston and Jonathan Wade, rookie Aaron Berry and newcomer Alphonso Smith. I'm not saying it was a mistake to cut Bly and King. Just a bit surprising. Defensive tackle Landon Cohen, meanwhile, saw the Lions overhaul his position in the offseason, but seemed to make enough plays in training camp and during the preseason to earn a roster spot. Instead, his spot went to Andre Fluellen. Finally, the Lions chose Aaron Brown over DeDe Dorsey for the final running back spot. Dorsey made two big plays in the preseason finale, but coaches chose Brown's speed and potential special teams contribution.
No-brainers: I give the Lions credit for releasing linebacker Vinny Ciurciu. He entered training camp as a player focused on special teams, but spent most of it filling in for injured middle linebacker DeAndre Levy. Ciurciu hasn't played much linebacker in his career, and unfortunately for him, the extended time revealed that he wouldn't be able to hold down the position should he be called on in a relief role during the season.
What's next: The Lions need to settle their secondary following this weekend of flux. Who is their nickel back? What about the dime? Will rookie Amari Spievey remain at safety or move back to cornerback to provide more depth? The team is also going to need to spend some more time looking for depth at linebacker. It wouldn't be a surprise to see them focus at that position over the next few days.
