Detroit Lions' Calvin Johnson is the best in the league, and barely human

(CBS/AP) - What can mere men do against Megatron? Wide receiver Calvin Johnson transformed into demolition mode in the second half of the Detroit Lions' incredible comeback against the Dallas Cowboys on Sunday. Detroit erased a 24-point deficit in the second half with defensive turnovers and a pair of touchdown receptions - including the game winner - by Johnson.

As Lions receiver coach Shawn Jefferson told the Detroit Free Press about Johnson, "We're witnessing greatness right here."

As Detroit continues to turn heads with their remarkable play and 4-0 record, a lot of the attention is on Calvin Johnson, currently the NFL's most productive receiver this season. The 6-foot-5 wide receiver has scored two touchdowns in each of the Lions' games this season and has racked up 321 yards on 24 receptions.

The numbers are impressive, but anyone who watched the game on Sunday knows that Johnson's ability goes far beyond simply making catches. That 23-yard touchdown catch Johnson pulled out of triple coverage is destined to be a highlight reel staple.

Johnson caught eight passes for 96 yards against the Cowboys, and tied Cris Carter's NFL record of catching two TDs in four straight games. He already was the first player in NFL history to do it in the first three games of a season, so he stretched that mark, too.

"The kid knows he's the best receiver in the league," Coach Jefferson told the Detroit Free Press. "He does. He knows it. But he's just as humble as humble can get."

That may be the only piece of good news for defenses: at least Megatron still thinks he's only a man.
