Drive president Steve Jbara told MLive.comthat the team will continue to play in the postseason and will wear a “Zeke” patch to honor its fallen teammate.

“They want to play, they want to play to remember him,” Jbara said. “I think they all were trying to wrap their heads around what Zeke would want and they all came out that they wanted to play, play hard and give it their best shot.”
