1) Why did the NFL swtich end zone sides between SB 44 and SB 45? Up to SB44, during odd numbered Super Bowls the NFC was on the left and the AFC on the right and it was reversed on even numbered SBs. Since SB45, the AFC is on the left and NFC on the right during odd numbered Super Bowls.
2) That said, if the end zones were reversed on this field, would the Steelers helmet still face right or would it face left and show the logoless side of the helmet?
