INDEPENDENCE, Ohio -- Cavs general manager David Griffin and coach Tyronn Lue were about 30 minutes late getting to the podium for the start of media day Monday.

The reason: About 10 minutes before they were supposed to speak, Griffin received a phone call from Raymond Brothers, Mo Williams' agent.

Williams wasn't going to make it out for training camp after all, Brothers told him. Williams had flip-flopped on his own decision to play for one more season and would in fact retire.

"Throughout the summer ... it was in debate on what Mo was going to choose to do," Griffin said. "He vacillated a little bit, and so we were planning on this eventuality throughout."

While Griffin said he felt "comfortable" with the Cavs' current point guard situation -- behind Kyrie Irving now is only rookie Kay Felder -- the team has on its radar free agents Norris Cole, Mario Chalmers, and Kirk Hinrich.

The Cavs have been in contact with all three players this summer, a source said, in anticipation of Williams' move. But the team, at least at this point, is in no rush to sign one of them, preferring to let the 5-9, 21-year-old Felder get his feet wet in camp and see if Lue can work his rotation properly without them.

For instance, in addition to Felder, LeBron James can (and often does) run the offense. Jordan McRae, who is expected to make the team, and Markel Brown, a non-roster invite who's played in the NBA with Brooklyn the last two seasons, are also in camp and could handle the ball.

Given the Cavs' salary situation -- they're way over the $94 million cap -- Cleveland cannot offer any free agent anything beyond a veteran's minimum to come here.

Cole, 27, a Cleveland State alum, is averaging 7.1 points and 2.8 assists per game in five seasons. He played the last 1 1/2 years with the New Orleans Pelicans, and in 45 games last season averaged a career-high 10.6 ppg. His last game was March 7.

Cole was friendly with LeBron James -- the two were both repped by agent Rich Paul and played together with the Miami Heat -- and James accompanied Cole to Cleveland State last season when the Vikings honored him during a home game. But Cole is no longer represented by Paul. Their business arrangement ended over the summer.

Chalmers is also James' former teammate with the Heat. He suffered a torn Achilles in March while playing for the Memphis Grizzlies, and was released after the injury.

Chalmers, 30, averaged a career-best 10.3 ppg last season. He was cleared to resume basketball activities in August.

Hinrich is the Cavs' oldest option from that list at 35, and his numbers have been in decline over the past few seasons. He was traded from Bulls last season (where he played 11 of his 13 seasons) to Atlanta and was used sparingly.

Hinrich is averaging 10.9 ppg for his career and is a 37.5 percent shooter from 3-point range, but has averaged less than 6 ppg in each of his last two seasons.

"We feel very comfortable with where we are at the point guard position, the versatility that we have to absorb that," Griffin. "We have other people that can guard the position. Because of LeBron, we have additional people that can also play the position offensively, and frankly we're really excited about finding out what some of the younger players on our roster can do. This is a training camp that for the first time since I've been here I think will be incredibly competitive, relative to roster spots themselves, and we're really excited about the guys that we have in camp who have a chance to earn a job."

Williams was an aging guard at 33 with 13 pro seasons under his belt and a balky left knee. He Tweeted last week he would return to the Cavs, after spending most of the summer telling people close to him that he intended to retire.

Williams is owed $2.2 million this season. If he files retirement papers with the league, he would forfeit his salary. But the Cavs can't make him do it -- for instance, Tim Duncan will be paid by the Spurs this season, as will Kevin Garnett by the Timberwolves, though they are newly retired. Griffin wouldn't comment on whether or not the Cavs were trying to negotiate a buyout with Williams.

The Cavs opened training camp Monday without starting shooting guard J.R. Smith, who is not yet under contract, and with new additions Chris "Bird Man" Andersen (38) and Mike Dunleavy (36).

Prior to Williams' departure, Cleveland had the oldest roster in the NBA with an average age per player of nearly 31.

"They talk about us being old and having an experienced team, but Kyrie's young, Tristan (Thompson) is young, K-Love's (Kevin Love) young, Shump's (Iman Shumpert) young, so, the core of our team, and what we're trying to do, they're young," Lue said. "Plus LeBron has the body of a 19-year-old, so, going forward I just don't think our team is old."
