Nate was a California kid. He actually projected as a TE when he was a high profile national recruit coming out of high school. A big athletic kid with good hands. He choose to stay close to home when he signed with UCLA.
People who follow college football on the west coast may know better than me but I think Jim Mora became the HC there at some point during Nates college career.
Anyway.. After a redshirt season Nate started as an OT as a frosh then moved to TE as a soph. Due to his size and athletic ability and the needs of the team Nate switched sides his JR year playing inside and outside d line.
Nate Chandler has shown a maturity and selflessness to change positions and also had the ability to have some success. He's a smart player and it was likely all of these qualities with diverse experiences and versatility that made our man Ron fall for him back when no one knew who he was or why we kept him around as a UDFA.
