Jayson Tatum supports Panthers and former classmate Matthew Tkachuk - ESPN

The Florida Panthers have some serious NBA star power supporting them ahead of their potential Stanley Cup Final series-clinching Game 5 against the Edmonton Oilers: Boston Celtics star Jayson Tatum.

Fresh off of his 31-point, 11-assist and 8-rebound performance in Game 5 of the NBA Finals, the new NBA champion sent a message to Matthew Tkachuk and the Panthers.

Tatum and Tkachuk attended Chaminade Prep together in St. Louis, Missouri.

«Tkachuk, go get it done tomorrow. One kid from St. Louis wins a championship today. Let's make it two tomorrow.»
