4. Number: 54

What it means: Total number of 20-plus-yard plays for the Lions' offense

NFL rank: 26th

Twentyman: New offensive coordinator Darrell Bevell wants his offense to have a tough, hard-nosed running game, and he wants to be explosive in the passing game.

"When we throw the ball, we want to be able to throw it down the field and get big plays," Bevell said this offseason.

That would be a bit of a change from what we saw last season, when Stafford's yards-per-attempt average was the lowest (6.8) in his past six seasons, and his 44 pass completions of 20-plus yards ranked 17th among the league's passers.

5. Number: 36.1

What it means: Detroit's third-down conversion percentage on offense

NFL rank: 25th

Twentyman: Looking at the stat sheet after each game, the three most critical areas to winning and losing are turnovers, performance in the red zone and third down percentage.

Being good on third down means teams are extending drives, keeping their defense off the field, likely winning the field position battle and hopefully scoring a few points along the way.
