Calvin Johnson is mortal after all. The Detroit Lions superstar has produced the greatest three-year receiving stretch in the history of the NFL, but dropped two passes that proved costly in a 18-16 loss Monday night against Baltimore. "Definitely," Johnson said, when asked whether his drops blunted Detroit's momentum. "We had some critical third downs, and I think we could have kept the drives going.'' The first drop came on a third-and-15 in the first quarter, when he gained separation over the middle from cornerback Corey Graham. He was wide open, and appeared to have only one man standing between him and the end zone. The other drop came on a second-and-9 in the second quarter. "It's uncharacteristic,'' Johnson said. "We had a good week of practice, seeing the ball. To have that happen in the game, didn't watch the ball (all the way in). It's as simple as that.'' Johnson finished with six catches for 98 yards, which is solid production, and he became the first receiver in NFL history to amass 5,000 yards in a three-year span. He's second in the NFL with 1,449 receiving yards this year. Johnson unquestionably is one of the game's greatest talents. But he unquestionably hurt his team against Baltimore. He now has 10 drops on the season, according to ProFootballFocus, which places him among the top 10 in the NFL. Quarterback Matthew Stafford has struggled to get up his completion percentage this season -- he was 31st entering the weekend -- but he's also been plagued by his receivers dropping passes. Even the great Calvin Johnson is not exempt.
