Coach Mark Crabtree knows what lies ahead for his Dublin Coffman High School football team in the second round of the playoffs.
The second-seeded Shamrocks will face third-seeded Toledo Whitmer on Friday, Nov. 9, in a Division I, Region 2 semifinal at Harding Stadium in Marion.
The Panthers, who are 9-2 and have won five games in a row, are led by a Division I college prospect at quarterback in Riley Keller. The 6-foot-1, 195-pound junior has completed 135 of 234 passes for 1,831 yards and 20 touchdowns.
"I have seen my share of good quarterbacks and you know it when you see one," Crabtree said. "(Keller) has some of the tools needed to be a guy to play at the Division I (college) level from what I see on film. But I'm only worried about one quarterback, and that's Ethan."
Senior quarterback Ethan Brown ran the Shamrocks' offense to near perfection in his final home game, a 27-10 win over seventh-seeded Westerville Central on Nov. 2 in the opening round of the playoffs as Coffman improved to 10-1.
Brown accounted for all four of the Shamrocks' touchdowns, scoring on runs of 1, 7 and 7 yards and connecting with senior wide receiver Matt Dorenkott on a 14-yard scoring pass.
Brown was 11-for-19 passing for 123 yards and rushed for 43 yards on nine carries.
"Statistically speaking, Ethan was not flashy, but the way he plays and runs our offense has been great," Crabtree said. "He had a really nice game and he has taken our offense and run it the best way he knows how. We're very pleased with how he has performed to this point."
Both quarterbacks are surrounded by good complementary players.
Keller has running back Kobie Myers, who has rushed for 570 yards and nine touchdowns on 129 carries. Myers scored the game-winning touchdown -- a 1-yard run on fourth down with 1 minute, 57 seconds remaining -- in Whitmer's 20-17 home victory over fifth-seeded Olentangy Orange in the first round of the playoffs Nov. 2.
Keller's primary target is wide receiver Dalan Layton, who has 59 receptions for 594 yards and nine touchdowns. Wide receiver Zach Walling has 33 catches for 375 yards.
"They run the spread and they have a really good quarterback," Shamrocks defensive coordinator Curtis Crager said. "Then again, everyone is good at this time of year. They are fast and physical."
Junior running back Moussa Diallo has returned from a hand injury to rush for 171 yards on 43 carries in the last two games for Coffman. Against Central, junior slotback Mike Drennen caught three passes for 36 yards and junior wide receiver Jameel Williamson had four receptions for 34 yards.
Both defenses also are coming off strong performances. The Shamrocks shut out Central in the second half, while Whitmer limited Orange to three points before the Pioneers' 14-point fourth-quarter surge.
"They play a 4-3 base defense and everything adjusts from there," Crabtree said. "They like to jump into an odd front, meaning they go with three down linemen in order to put in an extra linebacker or defensive back to fit the situation."
The Coffman-Whitmer winner plays top-seeded Reynoldsburg or fourth-seeded Olentangy Liberty in the regional final Nov. 16 at a site to be determined.
