Meaning behind Rams' trade for Morris

The looming roster cutdown dates have sent teams to the NFL trading post.

After the Arizona Cardinals shipped sixth-round choice Jorrick Calvin to Philadelphia for a rookie fullback, the St. Louis Rams made a similar move. They sent rookie fifth-round choice Hall Davis to the Washington Redskins for a conditional draft choice. The Redskins sent sixth-round rookie tight end Dennis Morris to the Rams, also for a conditional pick.

In both cases, teams parted with players they deemed unlikely to earn roster spots. They addressed depth issues along the way -- not necessarily for the regular season, but at least for the final exhibition games. Morris is listed as a tight end, but he's 6-foot-2 and 265 pounds, making him a candidate to get work at fullback. The Rams might want to protect starting fullback Mike Karney as they approach the regular season; if they can find a versatile backup for him, all the better.

The Rams remain in some flux at tight end. They have intriguing options in rookies Fendi Onobun and Mike Hoomanawanui. Veterans Billy Bajema and Daniel Fells remain in the mix.
