It looks like Green Bay Packers running back Eddie Lacy got coach Mike McCarthy's message.
In his third year in the NFL, Lacy suffered a major drop-off in production, which ultimately led to his benching. Many pointed to his weight, which was listed at 234 pounds, as the source of his on-field failures.
McCarthy never fully addressed the situation until after the Packers' season was over. Per Tom Silverstein of the Journal Sentinel, the coach said back in January that his running back had "a lot of work to do" and that he "cannot play at the weight that he played at this year."
There was no hidden message there. McCarthy made it clear to Lacy that he was in unacceptable shape. NFL Network's Ian Rapoport would later report that the team wanted the player to lose 30 pounds this offseason.
Two months into the offseason, the Packers coach has to like the progress he's seen from the 2013 Rookie of the Year (although it's not clear how much weight he has dropped thus far).
According to Silverstein, the photo in the tweet up top was taken on March 17. It surfaced two months after TMZ Sports reported that Lacy was in talks with P90X creator Tony Horton to try to get in shape.
Whatever method he is using right now, the results look good.
