Answer by taking a quote from the following article:

Elroy Leon "Crazylegs" Hirsch (June 17, 1923 - January 28, 2004) was an American football player, sport executive and actor. He was inducted into the Pro Football Hall of Fame in 1967 and the College Football Hall of Fame in 1974. He was also named to the all-time All-Pro team selected in 1968 and to the National Football League (NFL) 1950s All-Decade Team. A native of Wausau, Wisconsin, Hirsch played college football as a halfback at the University of Wisconsin and the University of Michigan, helping to lead both the 1942 Badgers and the 1943 Wolverines to No. 3 rankings in the final AP Polls.

In January 1945, the Cleveland Rams selected Hirsch in the first round (fifth overall pick) of the 1945 NFL Draft. In May, he announced that he would not sign a contract with the Rams, stating that he intended to return to the University of Wisconsin after his discharge from the military.  He ultimately opted not to play in the NFL, instead playing for the Chicago Rockets of the All-America Football Conference (AAFC). Hirsch chose the Rockets because they were coached by Dick Hanley, who had been Hirsch's coach with the El Toro Marines team. Hirsch played three seasons with the Rockets from 1946 to 1948. During those three years, the Rockets compiled a 7-32 record and won only one game in each of the 1947 and 1948 seasons. Hirsch later said the decision to sign with the Rockets was the worst decision he ever made.  In a remarkable display of versatility, Hirsch appeared in all 14 games for the Rockets in 1946, contributing 1,445 yards: 384 kickoff return yards and one touchdown; 347 receiving yards and three receiving touchdowns; 235 punt return yards and one touchdown; 226 rushing yards and one rushing touchdown; 156 passing yards and one passing touchdown; and 97 return yards on six interceptions.  In September 1947, Hirsch caught a 76-yard touchdown pass for an AAFC record. However, injuries limited Hirsch to five games in 1947. He was described in December 1947 as probably "the highest paid waterboy in pro football."  In the fifth game of the 1948 season, Hirsch sustained a fracture on the right side of his skull after being kicked in the head during a game against the Cleveland Browns. Hirsch did not return to action during the 1948 season, totaling 101 receiving yards and 93 rushing yards in five games.

Did Elroy win any championships with the Chicago Rockets?
During those three years, the Rockets compiled a 7-32 record and won only one game in each of the 1947 and 1948 seasons.
