Question: How long had Nomme Kalju been a team when Teever signed with them? Passage:After his contract expired in May 2012, Teever returned to Estonia and joined Nomme Kalju's beach soccer team. He was also part of Estonian national team that played 2013 FIFA Beach Soccer World Cup qualification matches in Moscow in the beginning of July. Teever then signed a year-and-a-half long contract with Levadia and was instantly added to the UEFA Europa League squad. He also got offers from Finland and Germany, but decided to stay in Estonia so he could have better chance to return to the national team. On 19 July 2012, Teever made his debut for Levadia when he came on as a second-half substitute in a Europa League match against Cypriot side Anorthosis. He opened his goal scoring tally on his Meistriliiga debut on 23 July 2012, when his injury time free kick found the net against Tallinna Kalev.

Question: How old was Rush's replacement who gave the team a top 10 at Nazareth? Passage:In 1995, Bill France, Jr. announced the official formation of the NASCAR SuperTruck Series by Craftsman. With Hornaday already signed to drive Dale Earnhardt Incorporated's No. 16 truck, the Spears family turned back to Bill Sedgwick, who would debut their white No. 75 Spears Manufacturing Chevrolet at PIR for the Copper World Classic. Sedgwick would finish 12th in the first ever truck race. Spears proved its competitiveness by winning the pole at Mesa Marin Speedway. Spears Motorsports's first season in the trucks netted them 1 pole, 6 top 5s, and 13 top 10s for a seventh-place points finish. Sedgwick left for Darrell Waltrip Motorsports in 1996, and Spears brought on driver Bobby Gill, who was a consistent top 20 finisher but released after Louisville despite gaining four top tens. Gill was replaced by Busch Series driver Nathan Buttke, who had 7 top 10 starts, but only 3 top 10 finishes and 7 DNF's. Buttke was released for Dan Press who also struggled and had 4 DNF's. Press was soon replaced by another West Series driver, Kevin Harvick, who had made two previous starts in the No. 79 Chevrolet at Tucson and Louisville, finishing in the top 20. Harvick would struggle with only an average season of mid pack finishes but garnered two 8th-place finishes. Harvick ran the full 1998 season except for Nashville, where Lonnie Rush Jr. drove the No. 75 truck but crashed. Despite three consecutive DNF's at the beginning of the year, Harvick and team rallied back to finish 17th in points, with 3 top 5s and 5 top 10s. Harvick would leave Spears for Jim Herrick's team in 1999, and was replaced by Rush, who struggled and was replaced by Marty Houston, who gave the team a top 10 at Nazareth. Houston returned in 2000, scoring 1 top 5 and 10 top 10s to finish 12th in points. His success raised the eyebrows of Armando Fitz, who got him into his Busch Series car for 2001. Another future USAR driver, Billy Bigley, took the reins of the No. 75, resulting in 1 top 5 and 8 top 10s for a 13th-place points finish.
