Input: Passage: Hoping to rebound from their home loss to the Vikings, the Cardinals flew to Gillette Stadium for a Week 16 interconference duel with the New England Patriots. Arizona would trail early in the first quarter as Patriots running back LaMont Jordan got a one-yard and a three-yard touchdown run. The Cardinals' east coast struggles continued in the second quarter as quarterback Matt Cassel completed a 15-yard touchdown pass to running back Kevin Faulk and an 11-yard touchdown pass to wide receiver Wes Welker, followed by kicker Stephen Gostkowski's 38-yard field goal. In the third quarter, Arizona's deficit continued to climb as Cassel completed a 76-yard touchdown pass to wide receiver Randy Moss, followed by Gostkowski's 35- and 24-yard field goal. In the fourth quarter, New England concluded its domination with Gostkowski's 30-yard field goal. The Cardinals would then get a meaningless touchdown as quarterback Matt Leinart completed a 78-yard touchdown pass to wide receiver Larry Fitzgerald. Original starting quarterback Kurt Warner (6/18 for 30 yards) was pulled in the third quarter via coach's decision. 
Question: How many yards was the Patriot's longest touchdown pass? 
Answer type: Number 
Output:
15.
