Matt and Calvin are both mentioned in this.

Good article.

4. Receiving Yards
Jerry Rice, 1995: 1,848 yards

Johnson was only 167 yards shy of Rice's single-season receiving yards record last year, and I feel like Johnson has a better season in him. He can make up that 167 yards in a quarter, if he chooses to. Obviously, health is key (as it is with all these records) for both Johnson and Stafford if this record is going to fall.

Titus Young can be a factor, too. He can develop into a better complementary receiver than Nate Burleson, and if he does, he can help free Johnson up a little bit. As good as they were in 2011, there's room for Johnson and the Lions offense to grow.
