Trying to snap a two-game losing streak, the Seahawks went home for a Week 9 duel with the Detroit Lions. Seattle would trail in the first quarter as Lions quarterback Matthew Stafford completed a 7-yard touchdown pass to tight end Brandon Pettigrew and a 29-yard touchdown pass to wide receiver Bryant Johnson, followed by kicker Jason Hanson getting a 41-yard field goal. Seattle would answer in the second quarter as running back Julius Jones got a 3-yard touchdown run, followed by kicker Olindo Mare nailing a pair of 37-yard field goals. In the third quarter, the Seahawks took the lead as Mare got a 24-yard field goal, while quarterback Matt Hasselbeck hooked up with wide receiver T. J. Houshmandzadeh on a 2-yard touchdown pass (with a failed two-point conversion). Seattle would increase their lead in the fourth quarter as Mare booted a 20-yard field goal. Detroit tried to rally as Hanson made a 50-yard field goal, yet the Seahawks would end the game with cornerback Josh Wilson returning an interception 61 yards for a touchdown.
Question: How many yards difference was there between Matthew Stafford’s touchdown pass to Brandon Pettigrew and  Matthew Stafford’s touchdown pass to Bryant Johnson?
