Calvin Johnson hasn't been himself this season. Is it fair to wonder if we're seeing the start of a decline for the great wide receiver?
The 29-year-old Detroit Lions star is on pace to finish with his lowest level of production since his rookie season. Johnson was widely considered the game's top wideout at the start of 2014, but a second consecutive season of injury woes -- combined with a marked decline in "wow" plays -- creates the possibility we've already seen the best of Megatron.
Johnson -- who missed three games and parts of two others with a high ankle sprain -- ranks outside the top 40 in both receptions (38) and yards (578) this season. His steep decline in production is a major reason why Detroit's offense has become the team's surprising Achilles' heel.
"I think defenses obviously are keying in on him," quarterback Matthew Stafford said. "He's the best receiver in the league and they know that, but it's on me to just throw him better balls and make sure we're on the same page."
Johnson has admitted his ankle still isn't 100 percent, and the Lions have faced some of the NFL's top defenses in the weeks after Johnson's return to the lineup. Still, there was a time when Johnson was an uncoverable entity. You can't say that right now.
