Huge rugby player has impressive workout for NFL scouts
Mailata is a 20-year-old, 6-foot-8, 346-pound Samoan rugby player who currently competes for a team in Sydney, Australia, and he showed that he has the natural athleticism to play at the NFL level. He had a 5.12-second 40-yard dash and a 4.67-second short shuttle, both of which are excellent times for a man his size.
