Which Cavs Player Really Defined No. 13 In Franchise History

Explore the storied significance of the number 13 in Cleveland Cavaliers history as the team gears up for a new season.

The Cavaliers are 13 days from the start of the regular season, and that number has a little franchise history attached to it.

The first player to wear No. 13 for Cleveland showed up back in 1982, and the list that follows includes a wide range of Cavs contributors, from short stints to one of the most durable runs in team history.

One of the earliest names tied to the number was Artis Gilmore, a legend in San Antonio before his time in Cleveland. He played in both the ABA and NBA for San Antonio, and the Spurs retired his jersey first in 1984.

By the time he got to the Cavs, he was in the final stretch of his career and played 67 games, averaging 11 points per game. That was well below his usual offensive production, but a back injury slowed him down late.

Even with that late-career dip, Gilmore is still regarded as one of the best ABA players ever.

Another No. 13 wearer had a more unusual place in league history. He played only 28 games for the Cavaliers, but he was the first undrafted player to start his first career game.

After the 1996 season, the Cavs released him. He spent time overseas before returning to the NBA in 1999.

Then there’s John Amaechi, whose name carries significance beyond the floor. In 2007, he became one of the first former NBA players to come out as gay.

Delonte West brought a different kind of value to the Cavs after being traded from Seattle. He became a defensive weapon, the kind of player who could be thrown at opponents of any size, and he fit as an important complement to LeBron James.

His Cleveland run eventually ended after legal trouble and off-court issues involving the team and LeBron. West retired from basketball at 28, and mental health struggles cut his career short.

The longest and most lasting connection to No. 13 belongs to Tristan Thompson. He spent 11 years with the Cavaliers, including a stretch where he played 447 consecutive games for the team. After leaving following nine years, he returned in 2023 and retired in Cleveland.

Thompson also carved out a place in franchise history in the box score. He’s one of only four Cavs players with 5,000 points and 5,000 rebounds, and despite standing 6-foot-9, he made a living battling for every board. In the record book, he ranks third all-time in rebounds and fifth in games played with 708.

It’s not the number most people think of as lucky. For Cleveland, though, No. 13 has a real chance to end up hanging in the rafters someday.

Cavaliers Sweep Exposed A Bigger Problem Than James Harden

The Cavaliers Eastern Conference Finals exit did more than end a season, it put a harsh spotlight on how fragile the margin can be when the shots stop falling and the mistakes pile up. Cleveland was swept by New York, and the series quickly turned into a lesson in how poor shooting, turnovers and uneven defense can overwhelm a team that looked dangerous only moments earlier. Even with talent spread across the roster, the issues that surfaced against the Knicks were bigger than any one player.

James Harden, Donovan Mitchell and Evan Mobley all found themselves part of the same larger problem, as Cleveland struggled to match New Yorks physicality and consistency on both ends. The roster still has to answer real questions about how it is built, especially after recent moves aimed at bolstering perimeter defense, and this postseason made clear that the fixes need to show up fast.

Cavaliers Have A Defensive Problem That Could Haunt Them All Season

Clevelands early-season defensive picture got a little murkier with Dean Wade set to miss the opener, because his value has always been tied less to scoring than to the kind of matchup flexibility that lets a staff breathe easier on the back end. He gave the Cavaliers a steady answer against bigger wings and forwards, the sort of assignment that can tilt a night when the opponent leans on size and skill at the same time.

The problem is the league keeps asking more from that spot, with forwards getting stronger across the NBA and more capable of punishing mismatches if a team is one body short. Cleveland brought in Peyton Watson, but his game projects more naturally onto perimeter matchups than onto the leagues most physical forwards, which leaves the Cavaliers staring at a defensive question they may have to solve on the fly before the season settles in.

Egor Demin Is Giving The Nets A Reason To Watch Closely

Brandin Podziemskis new five-year extension with Golden State is a reminder of how quickly young players can move from promising to indispensable, and it comes at a time when several teams are sorting out what their recent draft picks can become. For the Cavaliers, that kind of development arc is never far from the conversation, especially in preseason, where coaching staffs are looking for signs that a player can handle more than one job on the floor and still help a team win games.

Egor Demin has been giving the Nets plenty to examine on that front, with his stated interest in contributing in multiple roles and the kind of improvement coach Jordi Fernndez has already pointed to. Cleveland has seen a parallel type of value in Peyton Watson, whose versatility stood out in preseason play and drew notice from Kenny Atkinson for the ways he can affect the game beyond spotting up on the perimeter, a profile that always tends to matter when teams are searching for the next rotation piece.
