Greenville coach Mike Williams is worried, and he will be until the final horn Friday night at Tiger Stadium.

Williams makes his return to the high school coaching ranks official Friday when Greenville is host to Class 4A Daleville.

While Daleville has switched to a more open offense by resorting to the run-and-shoot, Williams said that his concerns this Friday are more about his team than the Warhawks.

"I'm worried about us not playing to the potential as far as playing aggressively," he said. "I'm worried about us missing assignments. But we've done all we could do as a coaching staff to simplify things for our guys. The ball is now in their court."

Williams said that a lot of the coaching aspect of offense and defense has been put on the back burner so that he can identify the best 11 players on offense, defense and specialty teams.

"It's all a matter of who wins the individual battles now," he said. "If all 11 out there win their individual battle then this football team can be successful."

Greenville did not participate in a preseason game this year since Williams became the Tigers' new coach just four weeks before Friday's season opener.

Daleville, however, did shut out Dale County 14-0 in a preseason game.

"They are not a physical football team, but they do have a lot of skilled athletes," William s said. "I expect them to try to beat us at the perimeter."

The Warhawk offense will be held by quarterback Raphael Jones.

Williams said in order to be successful this Friday against Daleville, the Tiger defense will have to be disciplined.

"We need to make good decisions and play assignment football," he said. "And we need to protect from the deep threat."

Whether the Tigers line up in the wishbone or in a spread offense Friday, Williams said that execution will be one of two keys to coming away with a win.

"Execution and being physical will be the keys to us getting a W in that win column Friday night," he said.
