Three years ago, Roy Williams was the Lions’ big-money rookie wide receiver. He was the seventh overall pick in the NFL draft. He had to buy chicken for everybody after road games and take the other receivers out to dinner.

Now that the Lions have an even bigger-money rookie wide receiver – Calvin Johnson, the second overall pick in this year’s draft – Williams is getting hungry.

“Trust me, I’m going to help him spend a little of that bonus money,” Williams said. “He’ll not only be responsible for the chicken this year, but I envision him taking care of the room service as well. It’s not just going to be one dinner for all the receivers. It’s going to be a couple of dinners. And I’m not talking Ponderosa, either. I’m thinking Morton’s.”

Johnson signed a six-year contract Friday that is reportedly the richest in Lions history. Its maximum value is $64 million, with almost $27.2 million guaranteed and another $4.5 million in bonuses he should earn easily by midseason, according to NFL.com.

To whom much is given, much is expected. The Lions are counting on Johnson to make an immediate impact, not just with the balls he catches, but with how his presence opens up the offense for others. Johnson said he was trying to keep a level head and live up to the hype. He was widely considered the best player in this year’s draft; now ESPN.com has called him a future Hall of Famer.

“That’s crazy,” Johnson said. “That’s their job. Hopefully I come out here throughout my career and prove them right.”
