2015 NBA Draft Combine Prospects the Cleveland Cavaliers Must Watch Most Closely

While the players and coaches just wrapped up an Eastern Conference Semifinals win over the Chicago Bulls, this is a big weekend for the Cleveland Cavaliers in other areas as well.

The 2015 NBA Draft Combine runs from May 13-17 in Chicago, with plenty of scouts, general managers and other front office personnel sure to be in attendance. The Cavaliers hold two picks in this June's draft, one in each round.

While Cleveland possesses one of the most talented rosters in the NBA, it is far from flawless. With Tristan Thompson, Iman Shumpert, Mike Miller, James Jones, Kendrick Perkins and Shawn Marion all potentially hitting the free-agent market this summer, the Cavs could have to plug multiple holes before the start of the 2015-16 season.

For GM David Griffin, this is a key weekend when it comes to scouting which players would best suit the Cavaliers in the first and second rounds.

With 62 total players expected to participate, here are the five Cleveland should be watching the closest.

Frank Kaminsky, C, Wisconsin

2014-15 College Stats: 18.8 points, 8.2 rebounds, 2.6 assists, 1.5 blocks

Height/Weight: 7'0.75", 231 pounds

Pro Comparison: Spencer Hawes

While it's likely Kaminsky will be snatched up well before the Cavaliers get to make their selection, this would be a dream pick for Cleveland.

After Kevin Love, the Cavs don't have a true stretch big man and have been using the undersized James Jones as Love's primary backup. Tristan Thompson and Timofey Mozgov do most of their work near the rim and aren't real offensive threats.

This is where Kaminsky would help. Despite standing nearly 7'1", the 22-year-old senior has an excellent outside touch for someone his size. He attempted 2.6 three-pointers per game, connecting on 41.6 percent. 

While he's limited defensively, the Cavs can use Mozgov or Thompson to cover the paint and allow Kaminsky to serve as a stretch 4 or 5, something no one other than Love can do.

Jerian Grant, PG, Notre Dame

2014-15 College Stats: 16.5 points, 3.0 rebounds, 6.7 assists, 1.7 steals

Height/Weight: 6'4.25", 198 pounds

Pro Comparison: Brian Shaw

A 22-year-old senior, Grant is one of the few players in college basketball who could step comfortably into NBA minutes right away.

As good as Matthew Dellavedova has been for the Cavaliers behind Kyrie Irving, many teams like to carry a third point guard on their roster. Grant would be a nice addition to the backcourt given his experience and playmaker mentality.

Irving and Dellavedova can both operate as spot-up shooters at times, making room for someone like Grant to come in and handle the ball. According to Jonathan Givony of Draft Express:

"

Grant's best attribute from an NBA standpoint clearly revolves around his playmaking ability. He is a decisive passer and an extremely unselfish player overall, making reads automatically and whipping the ball impressively all over the court. He has a tremendous natural feel for finding the open man regardless of where they are on the floor, being capable of making every pass in the book, be it high or low, and to cutters, rollers or shooters. Unlike many big guards, he's not a combo looking to make the transition to the point, he's already a tremendous distributor.

"

Grant has good defensive potential thanks to his 6'4" frame, something that would only improve by spending time around Iman Shumpert and LeBron James.

Jarell Martin, PF, LSU

2014-15 College Stats: 16.9 points, 9.2 rebounds, 1.8 assists, 0.7 blocks

Height/Weight: 6'9.25", 239 pounds

Pro Comparison: Brandon Bass

Martin is an athletic big who projects as a stretch 4 in the NBA.

Like Kaminsky, Martin's role would be to learn from Love off the bench while letting the Cavaliers run their normal offense when he enters the game.

A talented scorer and rebounder, Martin isn't a great defender yet, and that's OK. Cleveland can use Mozgov to cover for Martin's defensive inefficiencies while he develops.

Development is a key word here, as Martin is just 20 years old. A positive sign for his future is his reported ability to be coached. According to Randy Rosetta of the Times-Picayune, "Several NBA scouts have commented on Martin being the kind of player who will adapt to the pro level as a student of the game because of his reputation for accepting coaching well."

With so many great veterans to learn from, Martin would be a great fit for the Cavaliers late in the first round.

Terry Rozier, PG, Louisville

2014-15 College Stats: 17.1 points, 5.6 rebounds, 3.0 assists, 2.0 steals

Height/Weight: 6'2.25", 190 pounds

Pro Comparison: Mookie Blaylock

If the Cavs want a backup point guard who can play lockdown defense, there are few better than Rozier.

A floor general who was asked to score a lot at Louisville, Rozier is a Youngstown, Ohio, native and alumni of Shaker Heights High School.

One of the main attractions toward Rozier is his ability to push the ball in transition, which he describes as his best skill. His three-point shooting is still a work in progress, something the Cavaliers would need him to improve.

Given Irving's average defensive play this past season, adding Rozier to the rotation would be a nice upgrade on that side of the ball. He could certainly spell Irving for periods of time against some of the NBA's best point guards.

Cleveland won't need his big scoring numbers, but instead should target Rozier based on his pace, defense and experience at a major college program.

Larry Nance Jr., F, Wyoming

2014-15 College Stats: 16.1 points, 7.2 rebounds, 2.5 assists, 1.2 blocks

Height/Weight: 6'8.5", 227 pounds

Pro Comparison: Hakim Warrick

Besides the obvious reason why the Cavaliers should be interested in Nance Jr., the son of Cleveland's all-time best power forward brings a lot to the table.

What makes Nance Jr. so special is that he can impact a game without even touching the ball. Standing nearly 6'9", Nance Jr. can play either forward position and provides a ton of energy and defensive versatility. He showed the ability to play pick-and-roll D effectively, now a crucial part of the NBA.

Nance Jr. can score off the ball, using his athleticism to cut to the basket and get out in transition. He's quite a nasty dunker like his old man, too. "Larry still doesn't have a clue of how good he can be," Larry Nance Sr. told Terry Pluto of the Plain Dealer. "He will need the right (NBA) team to work with him, but I think he can play in the league."

With Marion retiring, the Cavaliers have an opening for a combo forward who plays defense and doesn't need the ball in his hands.

Where Nance Jr. will go in the draft remains to be seen. Most seem to have him as a second-round pick or going undrafted altogether. The Cavaliers certainly shouldn't target him with their first-round selection, but consider using their late second-rounder instead.
