"This was the toughest decision I ever had to make," Plattenburg said. "I love UCLA and the whole coaching staff. I love Coach Mora and Coach Meat (Demetrice Martin) and I know UCLA is doing big things and will continue to do big things.
"The thing for me is, since I was little, my dream has always been to play for USC. That's where my mom went to school and that's where I always wanted to play too. USC never offered me but as soon as Sark and Heyward got to USC, they told me they wanted me and that I was a big priority.
"This wasn't about depth charts or where I can play earlier. I know I'm not guaranteed anything. I might never play at USC or never make the NFL but at least I can give myself a shot. If I didn't take this opportunity, I would look back later on with regret and I just didn't want to do that."
Telling UCLA wasn't easy: "I was dreading that call but he was real cool with me and took it well. He wished me luck but said they still want to go after me and said I'll still have a spot there. I really love that UCLA staff a lot, I can't say enough about them but I had to follow my heart here and my heart was leading me to USC."
In Plattenburg, USC is getting one of the nation's most physical corners who has the toughness to move to safety if need be but the athleticism to stay at corner. He transferred from Corona (Calif.) Centennial over the summer and was named the DB MVP at the loaded NorCal NIKE Camp and earned a spot in The Opening.
He's a technically sound player, very competitive and has better speed and athleticism than given credit for. He can run but his best attribute as a player is his physical style and the edge he plays with. He has a chance to come in and make an early impact for the Trojans.
