Calvin Johnson came within 36 receiving yards of 2,000 in 2012. He broke Jerry Rice’s single-season record in 15 games. He had a streak of eight straight 100-yard games.

Yet quarterback Matthew Stafford said he thinks the Lions’ receiver could surpass his 1,964-yard effort in 2013.

“He thinks he can, which is all that matters,” Stafford told the NFL Network’s “NFL AM” last week after signing a three-year extension that includes $41.5 million in guaranteed money.

“That guy works harder than anybody I know, and he thinks he can get better, so I wouldn’t put anything past him. He’s a guy that can obviously run all of the routes — inside, outside — make all of the catches and is a smart football player and a really good teammate.”

Johnson also battled injuries in 2012. Last fall, Johnson said he suffered a concussion in a September loss to the Minnesota Vikings and nerve damage that made it tough for him to grip the ball.

Johnson, who missed time during training camp last year with a splint on his finger, appeared on the injury report multiple times last year with foot, ankle, knee and thumb injuries. He also reportedly played with broken fingers.

Despite those setbacks, he still did what he did. However, it seems unlikely that Megatron could top that record-setting season given that new running back Reggie Bush expects to catch a high number of passes, that Nate Burleson and Ryan Broyles expect to be healthy and that tight end Brandon Pettigrew should top 100 targets again.
