The Los Angeles Rams made a couple of moves on Tuesday to kick off their offseason. They decided to move on from both John Sullivan and Mark Barron.

Both moves were strictly made to free up cap space for the Rams. The Rams freed up almost $12 million by cutting both players, making them free agents.

That leaves the Rams with around $35 million in cap space this offseason as of now. There could be more moves to be made by Les Snead and company.

The only thing with Sullivan and Barron getting cut is that both of them were starters in 2018. That means the Rams will either need to stay in house or find their replacements this offseason.

The Rams will definitely need to make a decision soon as the NFL Draft is right around the corner. Here are three options that the Rams possess to replace Barron this offseason.

Sean McVay, Rams

3. Micah Kiser

One of the routes the Rams could take when it comes to replacing Barron is rolling with Micah Kiser. Kiser was the Rams fifth-round pick in last year's draft.

In college, Kiser was a tackling machine. In three seasons starting at Virginia, Kiser totaled 393 tackles, 33.5 tackles for loss, and 19 sacks.

At Virginia, Kiser finished third all-time in ACC (Atlantic Coast Conference) history in tackles. The only guys ahead of him were his teammate Quin Blanding and Luke Kuechly. That Kuechly guy is pretty good for the Carolina Panthers. The only question mark with Kiser is his inconsistencies in pass coverage.

The Rams need someone next to Cory Littleton who is serviceable in coverage but can help stop the run. Kiser can bring both of those things if he can improve upon his coverage skills this offseason.

The former fifth-round pick didn't get any run with the Rams in 2018 but don't be surprised if Sean McVay and Wade Phillips decide to let the second-year linebacker fill Barron's spot.

Brandon Marshall, Broncos

2. Brandon Marshall

No, this is not the Brandon Marshall you're thinking of. This is inside linebacker Brandon Marshall, not the wide receiver Brandon Marshall.

According to James Palmer, about a month ago the Denver Broncos informed Marshall that they weren't picking up his option. That move would ultimately make Marshall a free agent on March 13th,

Since then, Marshall has stated that he'd be open to returning to the Broncos still. Although, the Broncos haven't shown any signs that the feeling is mutual.

The 29-year old linebacker could be a nice veteran addition to a team like the Rams. In his time with the Broncos, Marshall has been to two Super Bowls, winning one.

Marshall was part of an elite Broncos defense that held a streaky Carolina Panthers offense to just 10 points in Super Bowl 50. The Broncos held Cam Newton to just 265 yards, one interception, and two fumbles.

Fast forward to now, Marshall could be looking for a new place to call home in 2019. The production speaks for itself when it comes to Marshall.

In five years starting for the Broncos, Marshall has racked up 420 tackles, 28 tackles for loss, and five forced fumbles. It so happens that Wade Phillips was the defensive coordinator of the Broncos in 2016.

When the new league year begins on March 13th, Marshall and Phillips could be reunited.

C.J. Mosley, Ravens

1. C.J. Mosley

The Rams could make a splash move by going after someone like C.J. Mosley this offseason. Just recently, the Baltimore Ravens decided not to franchise tag Mosley, allowing him to hit the open market.

With that decision, Mosley immediately becomes the best option in free agency at inside linebacker. He will also likely be the most expensive, although the Rams did just free up some money if they wanted to make a move for Mosley.

Since Mosley was drafted 17th overall in the 2014 NFL Draft, Mosley has been a rock in the middle of the Ravens defense. In those five seasons, Mosley has 597 tackles, 43 tackles for loss, 8.5 sacks, six forced fumbles, and nine interceptions.

Mosley is the complete package at inside linebacker. At 26 years old, Mosley is a perfect long-term solution for the Rams.

It's going to be hard to sign Mosley, as all 32 teams will probably be interested in signing him. The Rams need to at least probe the situation to see if bringing Mosley in is practical.

Could you imagine Littleton and Mosley together on the same defense? It could become reality this free agency if the Rams are able to land Mosley.
