Input: Question: Are the Atlanta Silverbacks still a team? Passage 1:A former England under-21 international, he began his career in Manchester United's youth team before joining Sheffield United in 2001. He soon became a vital player for Neil Warnock's "Blades", and was named on the First Division's PFA Team of the Year in 2002–03, before he helped the Bramall Lane side achieve promotion to the Premier League in 2005–06. After making a total of 302 appearances for the club, he was sold to Stoke City in August 2008 for £2 million. He struggled to break into the first team at Stoke, however, and was sent out on loan to Championship teams Preston North End (twice), Derby County, Barnsley and Leeds United. He joined Leeds on a permanent basis in January 2013. He joined Millwall on loan in January 2015, before he was released from Leeds in May 2015. He signed with Stevenage five months later and was voted the club's Player of the Year for the 2015–16 season. After his 18-month spell ended he joined Port Vale in July 2017.
 Passage 2:He served in the RAF during the war as a navigator on bomber aircraft. He was awarded the DFC for gallantry for saving the crew of his Halifax bomber over Hamburg. During the war he met Terence Rattigan who was then a wireless operator and air gunner. They appeared together in entertainment for fellow servicemen at RAF ground stations. After the war he completed a course at RADA and subsequently joined a company at Barnstaple in Devon. Shortly afterward he formed his own travelling company, the Sage Repertory Group, with £200 given to him by his mother and was joined by three other actors from Barnstaple. An advertisement in The Stage in 1949 offering actors no salary but a share of the profits was answered by John Osborne who joined the company in Ilfracombe. His company took their plays from village to village but enjoyed little success, they presented a summer residency at the Victoria Theatre on Hayling Island but this too was short-lived. Shortly after he collaborated on two plays with Osborne, the first Personal Enemy fell foul of the censors at the time, the second was An Epitaph for George Dillon.

On February 7, 1999, the Colorado Rapids selected Winner in the second round (twentieth overall) of the 1999 MLS Supplemental Draft. The Rapids released him, but the Kansas City Wizards signed him in March after Tony Meola and Chris Snitko were both injured during the pre-season. On March 20, 2000, Winner signed with the Connecticut Wolves of the USL A-League. In August 2000, he moved to the Atlanta Silverbacks where he played nine games.
