Cherokee (19-0-2) will face Timber Creek (17-2-2) in the boys' final, set for 6 p.m.
Lenape's girls, who also have won four consecutive state Group 4 titles, are tied with Shawnee's boys for the most consecutive Coaches Tournament titles. Shawnee's boys won four in a row from 2001-04.
"Winning five Coaches Tournament titles in a row would be a huge accomplishment for our program," Lenape coach Kevin Meder said. "It's such a grueling tournament with so many quality teams."
Lenape, which is set to play Shawnee in the South Jersey Group 4 semifinals on Monday, is led by seniors Katie Rigby and Emmy Duffy. But the Indians' greatest strength is their depth and balance.
"They have so many good players - I've been told their second 11 would be ranked in the Top 10," Gess said.
Haddonfield is led by senior midfielder Katie Johnston. The Bulldogs received a big boost Thursday from the return of senior Laurel Falana, who had missed three weeks with an illness.
Falana scored three goals as Haddonfield beat Barnegat, 7-1, to advance to face West Deptford in Monday's South Jersey Group 2 finals.
"They're big, strong, physical, and very good on set pieces," Meder said of Haddonfield.
While Lenape is a regular in the tournament, Haddonfield made a rare appearance this season. The Bulldogs have declined invitations in recent seasons because Gess believed the demands of the tournament would compromise his team's ability to compete for a state title.
"We went to the Coaches Tournament finals in 2007, and it really banged us up for the state tournament," Gess said. "We had to hold out a couple of kids who were injured, and if not for a couple of breaks, we could have been knocked out of the state tournament early.
"We don't have the depth of the bigger schools. While I think it is a great tournament, our No. 1 focus is on getting to the state championship and I will not compromise that.
