|Arguably the best player at his position in the draft, Vaccaro is expected to be selected in the first round by a team looking for an immediate starter in the secondary. He possesses great coverage ability and delivers a powerful hit that can dislodge the football. Scouts are impressed with his intensity and aggressiveness, which make him a major contributor on run defense as well. He's able to power through blocking receivers to get to the ball-carrier, and was used in various blitz packages with Texas. Vaccaro's rise was on display during his junior season, and he was so effective - earning All-Big 12 honors - that it seemed inevitable he would leave early for the NFL. He picked off two passes and knocked eight down while adding the only two sacks of his career. Instead, he opted to return in the hopes of helping the Longhorns to a BCS bowl. They didn't come close, going 9-4 and settling for a 31-27 win over Oregon State in the Alamo Bowl. Still, Vaccaro's value didn't take a hit. He led Texas with 104 tackles, while intercepting two passes and defending five others, forcing two fumbles and earning second-team all-conference honors. However, scouts were a bit put off after he disappointed at the combine by clocking in at 4.63 seconds in the 40-yard dash while leaping 121 inches in the broad jump - ranking among the worst performers in each category for his position. His 38-inch vertical leap was better, and it showed an ability to get to balls thrown to taller receivers in the red zone. Vaccaro may have an advantage adjusting to the NFL since his uncle is A.J. Johnson, who played in the league from 1989-95 and won a Super Bowl with Washington.
