This is a slide for the real dark horses: Players who are potentially available, and who people might not have on their radar, but could make an impact.
David Lighty - Once again, I'm not a big proponent of bringing Ohio State guys in to Cleveland teams, but Lighty is the type of player who could make an impact for an NBA team. Lighty is currently playing overseas and would probably welcome the chance to join an NBA team.
He is a solid jump shooter who has always played with a defensive mentality. The question is whether or not he is quick enough, and athletic enough to compete with the other shooting guards in the league.
E'Twaun Moore - A former Purdue standout, Moore is only seeing the court as a part-time role player for the Boston Celtics. Moore made a name for himself in college as a physical, hard nosed player who excelled on defense and who could shoot from anywhere on the court.
In his first year in the NBA, Moore hasn't had much of a chance to show what he can do at the next level, but it might be worth the Cavaliers' time to give him a chance. The question is, with a rapidly aging roster, whether the Celtics could be enticed to give up on him.
Dominique Jones - A second-year player out of the University of South Florida, Jones hasn't been able to see the court much for the reigning NBA champion Dallas Mavericks. Jones is a big-bodied shooting guard who brings interior toughness.
He is an excellent rebounder and can get to the hoop effectively on offense. He's not a great shooter at this point, but he could bring an element of toughness and a few interesting offensive wrinkles to the Cavaliers.
Lance Stephenson - Lance is currently a bench player averaging nearly 10 minutes per game for the Indiana Pacers. Stephenson is a strong player who prefers to play more of an inside and mid-range game. His outside shooting isn't always a thing of beauty, but he has shown the ability to get into the paint, back down other guards and put the ball in the hoop.
Defensively, Stephenson is strong, though not extremely quick, and he rebounds the ball well. The biggest downfall with Stephenson is an apparent attitude problem, which could be corrected with good coaching.
Xavier Henry - Henry was a highly touted recruit for the Kansas Jayhawks, and he performed well enough in his one-and-done college career to be drafted 12th overall in the 2010 draft. So far, Henry hasn't made much of an impact in the NBA.
A lefty, Henry's jump shot has been very inconsistent. The Hornets are a team with a plethora of wing players, which means the Cavaliers may be able to nab him and give him a chance to be the star everyone expected him to be.
Von Wafer - The Cavaliers are used to being frustrated by Von Wafer, who seems to always play well against the Wine and Gold. At only 26 years old, Wafer is in his sixth year in the NBA and he's with his seventh different team (Orlando Magic). He's had issues with coaches in the past, but he can score the ball and is actually a pretty good defender. The Cavaliers could consider Wafer, hoping age and experience would bring maturity.
Jordan Crawford - In his second year with the Wizards, Crawford has had some explosive games so far in his career. Crawford is a strong, very athletic player who loves to shoot the basketball. Sometimes, that love for shooting goes too far, as Crawford will throw shots up at any time, whether they're good shots or not.
He doesn't shoot a high percentage, but with a little coaching, Crawford may be able to tone down his craziness on offense and play in control. That would make him a dangerous player for the Cavaliers.
Names that everyone will want to consider, but not me (because they're either not a good fit, or because their current teams probably will not trade them): Monta Ellis, Nick Young, Joe Johnson; Landry Fields, Gerald Henderson, Evan Turner; Shannon Brown and George Hill.
