I'm nout doubting that at all. But those can be cheated, especially if he's been coached up. Laser time is hand start laser finish, which can be anywhere from a tenth to almost 2 tenths off of pure electronic timing. These kids can shoot the hand through, rock the start, etc. I work out at a place that trains players for the combines and there are definitely some games being played.
That being said, the point of my initial post is that I think he can be great. I like his film and would love, love to have him in Orange. However, I get queasy when people say this player or that player is a "must get." I think we have some excellent options out there (I love Tyler Thompson's film too) and Washington isn't going to make or break this program. We've seen it all from Ishaq to Lavar Lobdell. Offers and stars aren't all of it. Kids can make themselves great, just as your son is trying to do by getting his ass to the gym at 5 AM.
It's a major jump to the next level. Some kids have no problem adjusting to playing the game where every kid is as big, strong, and fast as you are. Some never adjust. I think Washington can absolutely do it, but he, like every other player to sign a LOI is no sure thing.
