Even in another bad, anonymous Grizzlies season, Gasol has continued to produce, scoring 15.7 points per game and grabbing 8.6 rebounds per game.
The Raptors reportedly offered Valanciunas and Kyle Lowry for Gasol and Mike Conley, but that deal was rejected by the Grizzlies.
They traded Marc Gasol to the Toronto Raptors; Shelvin Mack to Atlanta; and Garrett Temple and JaMychal Green to the Clippers.
But the last time that Memphis traded a Gasol brother, it led to Pau Gasol's first championship in 2009, with the Los Angeles Lakers. The 76ers and Bucks have also made major moves as the trade deadline nears, with the Sixers landing Tobias Harris and Milwaukee getting Nikola Mirotic.More news: Electronic Arts Stock Takes Off as Apex Legends Scores
"I think with a player like Marc, we had talked about it for some time, it lined it up well for us I think (Gasol is still) a very strong player".
The 34-year-old center leaves the Grizzlies as the all-time leader in points, blocks, and minutes played.
Gasol is eligible to become a free agent this offseason if he opts out of the final year of his $25.5 million contract due next year. The amount of his bonus (if not waived) will be applied to his $24.1 million salary.
Friday, beleaguered general manager Chris Wallace met the media, explaining the moves the Grizzlies made at Thursday's deadline, sending Gasol to Toronto, shipping out three other players for guys with upside and financial and roster flexibility, and moving forward. The 7-foot big man had surgery for a dislocated thumb December 12, and hasn't played in a contest since his procedure.More news: Virginians reeling as top 3 officials in government embroiled in scandals
Valanciunas is averaging 12.8 points and 7.2 rebounds this season with the Raptors. Valanciunas is a solid player, but he doesn't make much sense for the Grizzlies long term, and neither does Miles.
Leonard also has a player option for 2019-20, worth $21 million.
Memphis is now $668,000 below the luxury tax threshold. Casspi, 30, has been sidelined with a knee injury, and his return this season wasn't guaranteed. The 6-6 swingman is averaging 5.5 points.More news: Colin Kaepernick thanks Rihanna for her Super Bowl boycott
