"I've done all the research," said Freeman, who is 6-6, 238 pounds. "Kansas State is starting over and this is what I've always wanted to do. The time is right."
Freeman says he has been told by an NFL advisory committee that he could be a high second-round pick. But Freeman could work his way into the first round because of his prototypical size and arm strength.
Freeman said his decision might have been more difficult if Ron Prince had not been let go, but that playing for Bill Snyder was an attractive possibility, too.
"I hope to bring leadership and toughness to an NFL team," Freeman said.
It will be interesting to see where he gets slotted by the draft guru's of the world.
