NFL free agency is about to kick off, which should certainly help break the current monotony in the sports world due to just about everything else (or literally everything else) being suspended or canceled.

The 2020 NFL free-agent market is certainly an interesting one, as a whole lot of big names—especially at the quarterback position—could be changing locations.

As a result, the NFL landscape could look awfully different next season.

With that said, here are the five most interesting teams to keep an eye on entering free agency.

5. Baltimore Ravens

The Ravens looked like the best team in the NFL most of last season, as they went 14-2 and marched into the playoffs on a 12-game winning streak before being smacked around by the Tennessee Titans in the Divisional Round.

Yes, Lamar Jackson won the MVP award, and yes, the running game between Jackson, Mark Ingram and Gus Edwards was dynamic, but the Titans exposed Baltimore's rather gimmicky offense in the postseason.

As fantastic as Jackson is, that style of offense typically doesn't fly in the playoffs, which is why the Ravens need to put some more pieces around their exciting young quarterback this offseason.

The problem for Baltimore is that it has limited cap space to work with, so it won't be able to make a ton of moves. However, the Ravens should have enough space to at least bring in another wide receiver to provide Jackson with another reliable weapon.

As far as wideouts go, it's basically Marquise Brown and not a whole lot else for Baltimore. Picking up a veteran like Emmanuel Sanders could go a long way in making the Ravens' offense more versatile.

4. Indianapolis Colts

The Colts are intriguing for a couple of reasons.

First of all, they should have nearly $90 million in cap space, so unless they decide to be really cheap, they should be able to add a couple of impact players in free agency.

Second, their quarterback situation is kind of in flux, as Indianapolis does not seem to entirely trust Jacoby Brissett moving forward, which has some speculating that Philip Rivers could ultimately land in Indy.

I think Brissett is taking some unfair criticism, as he was left with virtually no weapons at his disposal during the second half of 2019 due to a rash of injuries. At the same time, though, the Colts are constantly seeing Brissett in practice, so maybe they just don't like what they are seeing.

Regardless, Indianapolis' roster will likely look quite a bit different next season, whether that means the Colts will be making a change under center or signing some other pieces to bolster the squad. Or maybe both? Who knows?

3. Tennessee Titans

The Titans just had one of the strangest seasons we have seen in quite some time.

Marcus Mariota began the 2019 campaign as the starter, but gave way to Ryan Tannehill just before the halfway point. Tannehill then somehow became a really good quarterback overnight, leading Tennessee to a playoff appearance and a trip to the AFC Championship Game.

Here is the catch: both Tannehill and running back Derrick Henry are set to be free agents, and while the Titans seem intent on bringing back Henry, they may want to upgrade Tannehill with a certain future Hall-of-Fame quarterback who has spent the first couple of decades of his career with the New England Patriots.

That's right: Tennessee is considered one of the top potential destinations for Tom Brady, and if the Titans are able to pry Brady away from the Patriots, it would instantly vault them near the top of most people's list of Super Bowl contenders.

While the most likely scenario is Tennessee merely running it back with Tannehill, we can't ignore the possibility of Brady joining the club, which would just be madness.

2. Dallas Cowboys

The Cowboys have some of the most cap room in the NFL going into this spring, but the thing is, most of that money—or at least a sizeable chunk of it—could end up being spent on two players.

Both Dak Prescott and Amari Cooper are set to hit free agency, and while many are expecting Dallas to slap a franchise tag on Prescott, it would still cost the Cowboys around $33 million for 2020.

Coupled with the fact that Cooper will presumably end up getting over $20 million annually, that will probably leave the Cowboys with a little over in $20 million in available cap space.

Dallas can still land another impact player or two with that cap room, but we also need to keep in mind that the Cowboys need to sign their draft picks, so how much they actually spend after bringing back Prescott and Cooper remains to be seen.

In addition, Dallas has a new head coach in Mike McCarthy, so it will be interesting to see his different philosophies in terms of how to build the roster.

But the main thing to keep an eye on is the budding situation between the Cowboys and Prescott. If they place a tag on him, he is surely not going to be thrilled.

1. New England Patriots

One of the greatest dynasties we have ever seen in sports could be hanging in the balance.

As was mentioned earlier, Brady will be hitting free agency next week, and while the idea of Brady returning to the Patriots seemed like a sure thing earlier in 2019, it now seems like a 50-50 thing.

Some have even gone as far as to say that they would be stunned if Brady re-signed with New England.

Really, none of us really have any clue what is going on behind closed doors, but there appears to be a legitimate chance that Brady could leave the Pats this month, which would send the NFL into a frenzy.

And if that happens, what do the Patriots do? Do they attempt a rebuild with Jarrett Stidham? Do they try to sign Rivers or another veteran signal-caller? Do they attempt to go into win-now mode with Stidham?

And what if Brady re-signs? New England will still have plenty of work to do, as the Pats are in dire need of offensive help. Will they sign a couple of receivers? Will they get a tight end?

The Patriots are faced with countless questions right now, perhaps more than we have ever seen in the Belichick era.
