How does Lamarcus Joyner fit with the Rams?

It was hard not to be excited when the St. Louis Rams drafted Lamarcus Joyner in the second round of the NFL Draft. Joyner is a little on the small side at 5'8, but he's a big playmaker. And the Rams need playmakers.

Just look at the play below and think to yourself "wow, how many players can do what Joyner just did?" 

Jeff Fisher said that Joyner is a plug-and-play nickel corner. That may be true, but there's no reason to assume that Joyner won't play the same role that Tyrann Mathieu played with the Arizona Cardinals. Mathieu played primary in the slot for the Cardinals and was a sub package safety. Joyner should be able to do the same thing for the Rams. A couple of months ago, I scouted Joyner -- you can find that article here -- this is what I came away with:

Joyner might be undersized, but he's an aggressive defender. I like him better in the slot than at safety. He can also be a good return man and special teams player. Obviously he will have trouble with bigger receivers, but he can play. He's a good tackler and if he can develop as a safety he could be a real good chess piece for a defense.

Joyner will be joining a defense that's a great fit for him. Rams defensive coordinator Gregg Williams loves blitzing and Joyner is a great blitzer and a good tackler. Joyner also possesses good hands and knack at creating turnovers. He's an aggressive player that isn't afraid to tackle. Since the Rams use their nickel defense a lot it won't create a big disadvantage if a team decides to run the ball. He should fit in well with current boundary cornerbacks Janoris Jenkins and Trumaine Johnson who are entering their third season.

The Rams are better off with Joyner than without him, and there shouldn't be a surprise as to why the Rams defensive staff was happy to be able to draft him.
