Smoot attended Mississippi State University, where he played for the Mississippi State Bulldogs football team from 1997 to 2000. He started his junior and senior years, and was a first-team All-Southeastern Conference selection both years, and a consensus first-team All-American as a senior. He was also a finalist for the Conerly Trophy in 2000.
Professional career
First stint with Redskins
Smoot was drafted by the Washington Redskins as the 14th pick in the second round of the 2001 NFL Draft out of Mississippi State. Many believed he was a first-round caliber player but because of questionable off-the-field problems many teams shied away from him. Afterwards, he proclaimed himself to be the steal of the draft. In Smoot's four years with the Redskins, he collected 16 interceptions, and formed an impressive duo with Champ Bailey.
Minnesota Vikings
Following a strong season as part of the impressive Redskins defense in 2004, Smoot left the club as a free agent to sign with the Minnesota Vikings. However, he was not able to duplicate his success in Minnesota. Smoot reportedly bulked up in the 2006 offseason. His playing weight was listed at 178 lb for the 2005 season and in May 2006 the press reported he weighed about 200 lb. He faced very stiff competition for the starting spot since the Vikings drafted cornerback Cedric Griffin in the second round and cornerback Ronyell Whitaker was named All NFL Europa. In the third game of the season against Chicago, Smoot sat out the opening drive reportedly for discipline reasons. Coach Brad Childress said that was between him and Smoot. In the 11th game of the season, Smoot was benched in favor of starting Griffin instead. Childress said the switch was merited in performance and Griffin had been doing an excellent job.
Smoot was at the center of the 2005 Minnesota Vikings boat cruise scandal involving several of his Minnesota Vikings' teammates. Some Vikings players had rented a boat on Lake Minnetonka and reportedly hired prostitutes to have a "sex party" on the boat. Smoot allegedly held a purple double-headed dildo and inserted it into the vaginas of two women who were lying on the floor in the lounge area. After one woman left, he continued to "manipulate the dildo" inside the other woman in front of the young crew. Formal charges for the Boat Scandal were filed on December 15. Smoot was also alleged to have organized the whole party, an accusation he denied. On May 2, 2006, Smoot pleaded guilty to disorderly conduct and being a public nuisance on a watercraft in connection with the Love Boat scandal. He agreed to pay a $1,007 fine and perform 48 hours of community service. Vikings owner Zygi Wilf said, in addition to community service, he would participate in numerous service events this season. NFL spokesman Greg Aiello said fines were likely, but Smoot would not be suspended. On September 9, 2006, the NFL imposed a fine equivalent to one game's salary against Smoot and former Vikings teammate Bryant McKinnie for their role in the Love Boat scandal, Smoot's fine was $82,352.
Car crash
Smoot broke his jaw in a single-vehicle crash in Mississippi on December 22, 2006, where he was spending the week. His jaw was broken in five different spots. As a result, he was out for the rest of the season.
Second stint with the Redskins
He was released on March 1, 2007 from the Vikings. On March 3, 2007, the Redskins signed Smoot to a five-year deal worth $25 million. He was released on March 4, 2010.
Business ventures
SMACK Energy Bar
In November 2007, Smoot launched his own energy bar known as SMACK Energy chocolate bar. The website for this endeavor appears to have been abandoned in 2008. No orders are being taken at this time.
In April 2010, Smoot announced that he planned to open up a Waffle House in Washington, D.C.. He planned to open the first restaurant in the area of 14th and U streets NW. However, due to D.C. zoning laws, he admitted in 2015 that he was looking at other venues, potentially in Northern Virginia.
Personal life
Smoot has advocated for the passage of the FIT Kids Act, federal legislation that would require school districts to report on students' physical activity while also distributing health and nutritional information.
On November 25, 2014, Smoot was arrested by the Loudoun County Sheriff’s Office on a domestic abuse charge against his former girlfriend, Valerie Jackson. Smoot was officially cleared of all charges on January 6, 2015.
