Saying he felt happier than he has in a long time, Todd Marinovich ended weeks of speculation when he decided Friday to enter April's NFL draft.

"I'm really relieved, it's a big weight off my shoulders," Marinovich said in a telephone interview. "Now I can just concentrate on preparing for a giant step. It's definitely the ultimate challenge, preparing for the NFL."I don't expect it to be easy, but I've worked hard my whole life and I expect to work even harder."
