well if that's Ed's son,...you will never doubt his toughness...Ed was a freak of nature and a hardcore baller.
He's terrific saw him often at Stanford but even coming out of HS he was rated 216th in the country by ESPN 82 out of 100, Scout.com had him the 27th rated RB in the class and both speculated he might be playing out of position, ESPN listed him as athlete not RB. He made a bunch of National All American teams, but people still downgraded for no obvious reason, IMO because he's a white RB.
I love him he returns kicks, he catches the ball, and despite not being huge he can run inside he's tough and he makes the first guy and often the second guy miss.
But I'll be very surprised if he doesn't slip a bit in the draft, NFL teams tend to follow the herd.
