WALTHAM — Jaylen Brown has given a hyphenated nickname — “Seven-11” — to himself and new teammate Jayson Tatum in reference to their respective jersey numbers, and the rookie said he’s fine with it.
The two young Celtics share all kinds of quaint connections. Brown was a rookie last year. Tatum will be a rookie in the coming season. Each was the third pick in his draft. Both their names start with “Jay.” And when they play together this summer, starting with Monday’s opener against Philadelphia in Salt Lake City, they could emerge as one of the most dynamic duos on the summer league circuit.
