But the biggest reason Jefferson is improved when it comes to blocking is his confidence, and his attitude toward blocking.
"I think the most important thing about blocking is wanting to block, and being physical with it,'' said Jefferson, a converted quarterback. "I know more now. I know that at any given time I won't go out there and get beat, and now that I learn more, and know more, I want to do it.
"I never had a problem blocking. It was just with the little technique stuff that was a big thing that I had to overcome.''
Jefferson, who is 6-foot-6, 245 pounds, is the leading candidate to be Rutgers' top tight end target.
After making the transition to tight end late in training camp last August, Jefferson made five catches for 108 yards, but inconsistencies as he learned to block cut into his playing time.
"I just want to be consistent in everything I do, as far as the blocking, the catching, all the little assignment stuff,'' Jefferson said. "Based on footwork, and stuff, I'm more consistent. I'm doing it more and more. Everything is not going 100 miles per hour. I'm more consistent.''
Schiano said center Howard Barbieri, who injured his left knee during Monday's practice, is out for the spring but will be ready for the start of the season.
"He's going to be ok,'' Schiano said. "He doesn't need surgery, so that's good.''
"I've been watching him and I'm impressed,'' Silvestro said. "The kid's got some natural talent. He's got a pretty good punch and good backstep. That's a good base.''
Givens to safety
Darrell Givens was moved from cornerback to safety, and Schiano spoke about it.
"Just tinkering around a little bit,'' Schiano said. "Trying to get the best people in position.''
