"I've played receiver my whole life, so that is where I like to play," Custis said. "I think I attack the ball. I go and get the ball real well and I catch in traffic. I get off the ball pretty quick, but I need to work on it. I'm working on my route running, and it's going pretty good, but I need to work on it more."
Custis caught 29 passes for 628 yards and 10 touchdowns as a junior. He also had eight carries for 116 yards and a touchdown, which is why schools are showing him strong interest.
In addition to his offer from UMass, where his brother, Sharif Custis, is committed, he said Rutgers could be next.
"That's what I am hearing, that they're close to offering," Custis said. "I'm supposed to go there (Dec. 15) for a practice and to check things out."
It would be Custis' second trip there in a month. He was in attendance for Rutgers' win against Army last month.
"I thought it was great," he said. "That was my first time being up there, and meeting some of the coaches personally. I really like their concept, and how they do things up there. I really like their campus. It taught me more about how Rutgers is and what their football (program) is about."
Custis' main contact with Rutgers is running backs coach Norries Wilson, who recruits Philadelphia.
"He's pretty down to earth," Custis said. "He makes you feel comfortable. He gets to know you a lot. He stays in contact with you. That's what I like about him."
West Virginia is also showing Custis plenty of interest.
"West Virginia is saying they saw some of my tapes and they like me as a player," he said. "They've been trying to get me down there but there really hasn't been a good time to go down there. They like my tape, though."
