The Broncos' defense limited Patriots' quarterback Tom Brady to 188 yards passing and no touchdowns, but their defensive effort was wasted by a poor performance from their inconsistent offense. The Broncos' only scoring play was a 33-yard field goal by placekicker Brandon McManus. In the first quarter, a fumbled punt by Jordan Norwood led to a 45-yard field goal by Patriots' placekicker Stephen Gostkowski. An interception off Broncos' quarterback Trevor Siemian by cornerback Logan Ryan resulted in the only touchdown of the game&#8212;a 1-yard run by Patriots' running back LeGarrette Blount in the second quarter. Gostkowski added two more field goals&#8212;a 40-yarder in the third quarter and a 21-yarder in the fourth. The Broncos wore their alternate navy blue uniforms for this game.
Question: How many more field goal yards did Stephen Gostkowski get in the second half than in the first?
Answer: 16
