"I think I did well. I had to sit out the last bit because of an injury, but everybody kept telling me I did well anyway, so I guess I did good."

Earn a college scholarship.
"I haven't thought about any real factors (for college) yet," he said. "I just want to play football, anywhere I can."
"I'm good at finding open holes, just finding out how to get open, and I've got good hands. I try to get better every day, I'm working on running crisper routes right now. I catch over 200 balls a day."
Haynes said he doesn't have a timetable set yet for a decision.
