The Lions went into their fourth and final exhibition game Thursday intent on taking a long look at Patrick Edwards a player they think can have a significant role on offense this year.

Matthew Stafford threw a bomb to Edwards on the first play from scrimmage that sailed well beyond Edwards’ reach. On the Lions’ next series Stafford overthrew Edwards after he beat his man deep again.

Edwards finished with a team-high three catches for 33 yards and the Lions routed the Buffalo Bills 35-13 at Ralph Wilson Stadium but the Lions’ No. 1 offense did little to calm fears about its lack of firepower that have been bubbling all summer.

Stafford played two series went 1-for-6 and finished with a 0.0 passer rating and the Lions’ starting offense playing without Calvin Johnson and Reggie Bush failed to score a touchdown for the third time in four games.

Lions coach Jim Schwartz said afterward that he wasn’t concerned with his offense’s lack of rhythm and players from Stafford to receiver Nate Burleson did their best to diffuse talk of any inconsistency in the passing game.

“I think we’re right where we need to be” Stafford said in a halftime interview with WXYT-TV. “Keep progressing like you said. Get some of our guys back on the field and go out there and get ready for (next week’s season-opener against) Minnesota.”

Said Burleson: “I think we did pretty good for how we had to patch things together. I’m excited for what we’ve got going on this year. I think once everybody’s on the field this could be one of the better offenses we’ve had in the Detroit Lions uniform.”

The potential for that is there.

Johnson is the best receiver in the NFL and Bush is the complementary back the Lions have lacked for most of his career but the two spent precious little time on the field together during training camp as Johnson nursed a sore knee.
