"I was watching Enter The Dragon, and Bruce Lee was saying that when you punch, punch three inches beyond that point," Summers said. "So when I block, I try to attack him and block beyond him. And if you get guys to stop moving their feet, that's when you've got them."
Summers rushed for more than 1,000 yards as a senior at Oakland's Skyline High School in 2002. Yet coming to an offense where he would primarily be blocking back is fine by him.
"My first couple of years in high school, I was mostly a blocking back," Summers said. "Then I started carrying the ball more and got away from it. But blocking comes natural to me - my thing is to help make big plays whenever possible. If I do something that can help the tailback score, then I feel like I've scored too."
His eagerness for blocking stems not so much from a particular fondness for one facet of the game as it does something larger.
"It's beyond a passion for blocking, it's a passion for football," Summers said. "Everytime I get on the field I want to do the best I can. It doesn't matter if I touch the ball or not."
After practice, Summers usually spends 15 to 30 minutes blocking the heavy bag and working on the blocking sled. While he's hard-pressed to identify a preference between pass or run blocking, he does acknowledge the more technical aspects of pass blocking while also explaining what's necessary to perform a pancake block.
"First, you have to hit him high and straighten him up," Summers explained. "Once you've stood your man up, then you hit him lower and drive him back, and hopefully down."
While he didn't enroll at Cal until this past spring, Summers was a regular fixture at Memorial Stadium this past fall.
"I was out here for all the games," Summers said. "It was exciting to be here and I was really proud for the program. I'm really happy to be here, and to be close to home where my friends and family can see me. It's nice to see how many local recruits that we've been getting and it's exciting to play with people you know."
With Chris Manderino and Byron Storer topping the fullback depth chart, going into the fall, Summers is most likely to make an immediate impact on special teams.
He won't be hard to miss. Just listen for #34.
