Costello will join TD Systems Baskonia on a three-year deal.

EDGE Analysis

After playing for Herbalife Gran Canaria for his past two seasons, Costello will now play for TD Systems Baskonia. Costello managed to record season averages of 11.7 points, 6.1 rebounds, 1.4 assists and 1.3 blocks for the 2020-21 season.

Costello posted 20 points (6-7 FG, 8-9 FT), eight rebounds and two blocks across 21 minutes during the Pistons' 102-84 win over the Pacers in a Las Vegas Summer League game Monday.

EDGE Analysis

Costello is looking to eventually carve out a reserve frontcourt role behind Andre Drummond and Thon Maker, and Monday's showing was certainly a good start in that regard. The former Michigan State Spartan averaged 10.4 points, 6.2 rebounds and 1.2 assists over five games with Italian team Sidigas Avellino last season, and it appears the brief experience may have helped further his skills ahead of his current summer league tenure.

Costello signed a contract Thursday with S.S. Felice Scandone of the Italian League, Emiliano Carchia of Sportando.com reports.

EDGE Analysis

Costello will head to Europe after attracting limited interest in free agency from NBA clubs when his two-way contract with the Spurs expired at the beginning of July. During his inaugural season in the NBA, Costello appeared in just four games and played eight total minutes. The big man out of Michigan State ended up seeing most of his time in the G League with the Spurs' affiliate in Austin.

Costello accounted for with 16 points (6-8 FG, 1-1 3Pt, 3-3 FT), seven rebounds, four blocks, four assists and two steals during Tuesday's 109-105 loss at the Memphis Hustle.

EDGE Analysis

Costello arguably finished with his best game of the year Tuesday, as he reached double-figures in scoring and provided at least one tally in every major statistical category. The former Michigan State standout is contributing a fine 8.2 points and 7.0 rebounds for Austin this season.

Costello has agreed to sign a two-way deal with the Spurs, ESPN's Zach Lowe reports.

EDGE Analysis

Costello was a standout during the NBA Las Vegas Summer League earlier this month, pulling down an event-best 12.3 rebounds per game as a member of the Timberwolves' squad. The undrafted 2016 prospect won't be in line for immediate playing time in San Antonio, but the two-way contract allows for Costello to develop in the G-League.

Costello was waived by the Grizzlies on Monday, Michael Wallace of Grizzlies.com reports.

EDGE Analysis

Costello made a valiant effort in his attempt to make the roster and was one of the last cuts to get the Grizzlies' roster down to the 15-man maximum, but was unable to lock up one of those final spots. Costello saw limited action throughout the preseason, but the Grizzlies liked what they saw and he could be an option to join their D-League affiliate, the Iowa Energy.

Costello was signed by the Grizzlies on Thursday.

EDGE Analysis

Costello went undrafted in June after spending his collegiate career in Michigan State, but was signed to a partially guaranteed contract with the Hawks and spent training camp on their roster. He was waived by the Hawks earlier this week, but the Grizzlies want to get a quick look at him prior to the regular season. Costello is not expected to make the regular season roster and this is likely just an audition for an opportunity to play for their D-League affiliate, the Iowa Energy, to start the season.

Costello was waived by the Hawks on Monday, Chris Vivlamore of the Atlanta Journal-Constitution reports.

EDGE Analysis

Costello signed a partially guaranteed deal with the Hawks back in June, but ultimately couldn't make it past the team's final roster cuts as training camp winds down. He appeared in just two preseason games, playing just 18 minutes and recording eight points and seven rebounds in that time. Costello's most likely destination now is either the D-League or a contract with a team overseas.
