Austin Seferian-Jenkins said he played about 20 pounds overweight last season with Washington and that it hurt his production.
Seferian-Jenkins said he was asked to block more for Washington last season, so he added weight to do so. Though, he learned that blocking was more about technique and less about weight.
"I could have done a better job (overall)," Seferian-Jenkins said. "And, I was a little heavy, I can admit that. I shouldn't have been that heavy, but now I am at the right weight."
Seferian-Jenkins weighs 262 pounds now.
Seferian-Jenkins' receptions dropped from 69 to 36 last season. He had a bumpy start to the season when he was suspended for the opener as punishment for his DUI in March of last year. The reduced numbers led to conjecture that Seferian-Jenkins' season was influenced by the mistake.
"The DUI did not affect me," Seferian-Jenkins said.
Most questions Seferian-Jenkins fielded Thursday were about his arrest. He was even asked if he had should be considered a character concern for prospective teams. He repeated the arrest was in the past and that he's in no way a character risk.
Seferian-Jenkins was also asked about some past tweets from "draft experts" who said scouts wondered about his practice habits.
"I don't think you win the John Mackey Award having bad work ethic," Seferian-Jenkins said.
Seferian-Jenkins also said he was not coming back to Washington after his junior season whether Steve Sarkisian stayed or not.
"He knew," Seferian-Jenkins said.
At the combine, Seferian-Jenkins said he hopes to run around a 4.6 in the 40-yard dash. Rob Rang, a draft analyst for NFLDraftScout.com and CBSSports.com, said scouts want to see multiple things from Seferian-Jenkins at the combine.
"I do believe (the 40-yard dash) an important test for him," Rang said. "He's a smooth athlete, not an explosive athlete on tape so if he can run anything 4.65 or lower I think it can help boost his stock.
"The interview is definitely the most import thing for virtually every player here. Medically as well (to show his pinkie is healed). What he does best is catch the football. I would think that the bench press is also important for him. For a guy who was asked to to block as often as he was, he wasn't known as a physical blocker so he needs to show some explosive strength."
