With NBA free agency officially beginning, all eyes will undoubtedly be on the big stars hitting the open market. 

In a stacked class of free agents, most of the focus will be on superstars such as LeBron James, Paul George, DeMarcus Cousins and Chris Paul. 

But because of the attention on the All-Stars, there are good players who will fly under the radar this summer. 

Here are five of the best under the radar free agents: 

Tyreke Evans

The point guard enjoyed one of his most productive campaigns with the Memphis Grizzlies this season as he was one of only three players who averaged at least 19.0 points, 5.0 rebounds and 5.0 assists while shooting 39 percent from three-point range.

To put these numbers into perspective, Stephen Curry and Kevin Durant were the other two players to post these stats. 

Still only 28, Evans should receive strong interest as he proved his fitness last year and played at a high level. 

Will Barton

The shooting guard has been one of the most consistent bench scorers in the league during his time with the Denver Nuggets and also did damage as a starter this season too. 

He put up 15.7 points and 4.1 assists and would provide a boost to any team's offence with his scoring ability.

There will definitely be a market for Barton this offseason as he's a player capable of scoring at will (excuse the pun).

Kentavious Caldwell-Pope

KCP signed a huge one-year deal with the Los Angeles Lakers last season and enjoyed a solid campaign with the Purple and Gold where he averaged 13.4 points and 5.3 rebounds per game. 

He's a reliable 3-and-D role player and would be a great complementary piece on any team.

Calwell-Pope may not receive another $17 million salary and is unlikely to return to the Lakers as they target marquee names but there aren't many better two-way players available.

Isaiah Thomas

It would've been crazy to suggest this 12 months ago but Thomas has almost become the forgotten man and there's very little talk about his free agency. 

He may be recovering from surgery on his troublesome hip but we must remember that he's a two-time All-Star and still a reliable scorer in the NBA. 

The veteran is working extremely hard to get back to 100 percent and will have a point to prove next year. He won't get a max contract but on a reduced deal, he should interest several teams.

Wayne Ellington

The 30-year-old established himself as a great three-point shooter with the Miami Heat this year as he connected on 39.2 percent of his attempts from beyond the arc. 

In the last two seasons, he's taken his game to new heights and has proven he can be productive as a starter or off the bench.

With the demand for outside shooters, he would be a real asset and could be in for a significant pay rise.
