Cleveland Cavaliers roster is already complete but the team needs more work despite the Big 3 of Lebron James, Kyrie Irving and Kevin Love. Greg Monroe would have helped but the acquisition is still uncertain.

The Bleacher Report said that adding Shawn Marion and Mike Miller to the Cleveland Cavaliers roster is not enough to contend for the title, although with the help of its up-and-coming stars Dion Waiters and Tristan Thompson.

But it said that there's still much to be done for the Cleveland Cavaliers roster because neither Lebron James and Kevin Love are considered as rim-protectors.

"Looking over the Cavaliers roster, the main weakness is indeed the 5 spot where oft-injured Anderson Varejao and Brendan Haywood represent the team's two best options," it said. "Cleveland is so thin at center that coach David Blatt is even considering using 6'9" forward Tristan Thompson as his starter."

Brendan Haywood has a lifetime average of 1.4 blocks per game but he's a question mark as he's still recovering from foot surgery. Varejao, meanwhile, only averages 0.6 blocks per game and Thompson has a measly 0.4 blocks-per-game average.

This is where Greg Monroe, a high leaper who averages 1.5 blocks per game, can help the Cleveland Cavaliers roster. However, it will cost the team in order to sign him as the Detroit Pistons center is not about to take a discount for a chance at a championship.

According to Larry Coon of Basketball Insiders that Greg Monroe "didn't take the risk of signing a one-year qualifying offer contract because he intended to take a mid-level salary next summer."

"You can be sure, he wants to have a good season, and then he wants to get PAID. Cleveland is already committed to $74 million next season, with the cap projected to be $66.3 million. All things being equal, I think the Cavs' chances of landing Monroe are pretty slim," he wrote.
