On Friday, the 76ers officially announced in an official release that they signed wing Lonnie Walker IV after his brief stint overseas. Reports surfaced earlier in the week that they would sign the Pennsylvania native, but it was not made official until after the 76ers' loss to Boston.

Here are the three biggest takeaways for the Philadelphia 76ers in a blowout loss to the Boston Celtics at home.

The Celtics looked every bit their dominant selves in their win over the 76ers despite coming out of the All-Star break.

Payton Pritchard made eight 3-pointers and scored 28 points, Jayson Tatum finished with his fourth career triple-double, and the Boston Celtics beat the Philadelphia 76ers 124-104.

The Boston Celtics returned from the All-Star break by cruising to an effortless 124-104 victory over the Philadelphia 76ers on Thursday night. And as he has done for much of the season, Payton Pritchard delivered the goods for the Celtics off the bench, helping them salt this game away early in the second half.
