After winning the Super Bowl, it might be tough for a player to have the drive and motivation to do it all again.
Philadelphia Eagles wide receiver A.J. Brown is a perfect example who admitted in a social media post a few days after the Super Bowl title in February that winning it had worn off and wanted to dominated defensive backs on the field. This might be a rare case, but at least Brown was honest about his thoughts.
During the season, the Eagles have started 4-1, but it has not been smooth by any means.
