Context: Trying to end their three-game skid, the Rams flew to Qwest Field for an NFC West rematch with the Seattle Seahawks.  In the first quarter, the Rams struck first with rookie DE Victor Adeyanju returning a fumble 89 yards for a touchdown.  Afterwards, the Seahawks responded with QB Seneca Wallace completing a 3-yard TD pass to WR Darrell Jackson.  Then, St. Louis had kicker Jeff Wilkins nail a 40-yard field goal.  In the second quarter, Seattle took the lead with Wallace completing a 15-yard TD pass to TE Jerramy Stevens.  The Rams responded with Wilkins's 42-yard field goal.  In the third quarter, Wilkins gave St. Louis a 35-yard field goal for the only score of the period and the lead.  In the fourth quarter, the Seahawks responded with WR Nate Burleson returning a punt 90 yards for a touchdown.  The Rams retook the lead with RB Steven Jackson's 14-yard TD run, yet it was followed up with a failed two-point conversion.  However, just like earlier in the year, Seahawks kicker Josh Brown came out with the win, as he kicked a 38-yard field goal. With the loss, the Rams fell to 4-5.

Question: How many more field goals did Wilkins kick compared with Brown?

Answer:
2
