The 76ers made a last-ditch effort to keep Jimmy Butler on the roster, but he didn't bite the bullet.

According to NBC Sports, which cited a source close to the situation, the Sixers offered Butler a five-year max contract worth $190 million before he turned it down to instead take a four-year deal worth $141 million from the Heat.

The report noted Butler simply "wanted to move on" from Philadelphia, suggesting that "perhaps the Sixers put the offer on the table with the understanding that Butler wouldn’t take it."

Philadelphia agreed to send Butler to Miami in a sign-and-trade on Sunday, and received Josh Richardson in return.

It was also reported that the Sixers re-signed Tobias Harris to a five-year deal worth $180 million and added Al Horford on a four-year deal worth up to $109 million.

Butler, 29, began the season with the Timberwolves before he was dealt to the Sixers in mid-November. He averaged 18.2 points and 5.3 rebounds while shooting 33.8 percent from 3-point range in 55 regular-season games with Philadelphia.
