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. CANNOTANSWER

Did he play any other sports at that time?

Svar genom att ta ett citat från följande artikel: Elroy Leon "Crazylegs" Hirsch (17 juni 1923 - 28 januari 2004) var en amerikansk fotbollsspelare, sportchef och skådespelare. Han inleddes i Pro Football Hall of Fame 1967 och College Football Hall of Fame 1974. Han blev även uppkallad till det all-time All-Pro-lag som valdes 1968 och till National Football League (NFL) 1950-talets All-Decade Team. Hirsch, som var infödd i Wausau, Wisconsin, spelade collegefotboll som halvback vid University of Wisconsin och University of Michigan, och hjälpte till att leda både grävlingarna 1942 och Wolverines 1943 till No. 3 rankningar i finalen AP-undersökningar. I januari 1945 valde Cleveland Rams ut Hirsch i den första omgången (femte totalkvalet) av 1945 års NFL Draft. I maj meddelade han att han inte skulle skriva kontrakt med Rams, och uppgav att han hade för avsikt att återvända till universitetet i Wisconsin efter sin avskedsansökan från militären. Han valde slutligen att inte spela i NFL, istället spela för Chicago Rockets i All-America Football Conference (AAFC). Hirsch valde Rockets eftersom de coachades av Dick Hanley, som hade varit Hirschs tränare med El Toro Marines-laget. Hirsch spelade tre säsonger med Rockets från 1946 till 1948. Under dessa tre år sammanställde Rockets 7–32 rekord och vann endast en match under var och en av säsongerna 1947 och 1948. Hirsch sade senare att beslutet att skriva på med Rockets var det värsta beslut han någonsin fattat. I en anmärkningsvärd uppvisning av mångsidighet, Hirsch dök upp i alla 14 spel för Rockets i 1946, bidrar 1,445 yards: 384 kickoff return yards och en touchdown, 347 mottagande yards och tre tar emot touchdowns, 235 punt return yards och en touchdown, 226 rushing yards och en rushing touchdown, 156 passerar yards och en passerar touchdown, och 97 return yards på sex avlyssningar. I september 1947 fångade Hirsch ett 76-yards touchdownpass för ett AAFC-rekord. Skador begränsade dock Hirsch till fem matcher 1947. Han beskrevs i december 1947 som troligen "den högst betalda vattenpojken i proffsfotboll." I säsongens femte match 1948 fick Hirsch en fraktur på höger sida av skallen efter att ha blivit sparkad i huvudet under en match mot Cleveland Browns. Hirsch återvände inte till aktion under säsongen 1948, totalt 101 mottagarvarv och 93 rusande varv på fem matcher. CANNOTANSWER Spelade han någon annan sport vid den tiden?
