Sumler, who is the No. 24-rated receiver by Scout.com, holds close to 20 offers, including the one he received from Rutgers in March.
"I like that they had Tim Brown up there,'' Sumler said. "He's a Miami person, and he's not that big of a guy, and he had a pretty successful career up at Rutgers.''
The 5-foot-7, 160-pound Brown, who attended Miami Northwestern High, had a team-leading 55 catches for 1,150 yards and nine touchdowns as a senior. He ended his career with a school-record 20 touchdown catches.
Sumler is also enthralled with Fleck, who stopped by Christopher Columbus High twice in the spring. The two also talk on the phone regularly.
"I've built a good relationship with coach Fleck,'' Sumler said. "I would love to have young coach that knows what he's doing, and can coach me throughout my college years. I like that he's a young coach and he knows what he's doing. He informs me about everything I need to know about Rutgers, and the football team.''
Sumler's summer trip to Rutgers will be contingent on money.
"My parents told me I was doing good in school this year,'' Sumler said. "I'm going to college for free, so I might as well get a vacation. I was going to stay with my cousin and my aunt for two or three weeks, and my dad said if I was going to be out there that long, I might as well go see some of the schools that I like.
"When I come back, I'm going to see how we're doing financially and see if I can get up there to the north and see some schools.''
And which northern schools does Sumler have high on his visit list?
"I would love to go see Rutgers, and I was thinking maybe about Wake Forest,'' Sumler said. "I got an offer from Cincinnati, and I was really interested in that offer, so if possible, go and see Cincinnati.''
The summer tour should allow Sumler to pare his list, but he said an announcement on his college choice may not happen until January, or even signing day.
"I would love to take my official visits and get a better feel for (the schools),'' he said. "I'm travelling now just to break them down a little more and try to get a top 10, or a top five. If I know for sure, I wouldn't be hesitant to commit.''
Wherever Sumler winds up, academics will not be an issue. His mother has been elementary school teacher for more than 30 years, and he recently scored an 1130 on his SATs.
"She also enforces education first, education first,'' he said. "So, academics always come first.''
