AMES, Iowa -- Like many downtrodden programs, Iowa State has often struggled to find enough defensive linemen who can make a big impact on the field.The Cyclones might be in decent shape next year.Last week, Iowa State signed a pair of junior college linemen, Ray Lima and Matt Leo, and wide receiver Matt Eaton. The Cyclones were already set at receiver before the addition of Eaton, but Lima and Leo are expected to play immediately for a unit that looked pretty thin.Were not backing down from anyone in recruiting, coach Matt Campbell said. For us to get to where we need to go, the offensive and defensive lines are critical to us.Iowa States biggest defensive loss was tackle Demond Tucker, a two-time second-team All-Big 12 selection.Having Lima ready to replace Tucker would be a best-case scenario for the Cyclones. Lima was rated among the best junior college defensive tackles available by some recruiting publications despite redshirting last season. In 2015, Lima has 21.5 tackles for loss and seven sacks for El Camino Community College in California.Lima, who also drew interest from Oregon, Arizona, Arizona State, Colorado, TCU and California, will likely be more of a run stopper at Iowa State.Ray has got everything you want in an interior defensive lineman. Hes got elite twitch. Hes got really good length, Campbell said. Hes got every factor in terms of leadership.The Cyclones lose another lineman that earned second-team All-Big 12 honors in end Jhaustin Thomas.Leo might be more of a project than Lima, but he appears to have a ton of potential.Leo grew up in Australia, where he played professional rugby briefly before moving to the U.S. to take up football. Leo showed enough as a sophomore for Arizona Western last season to earn top-50 junior college rankings by ESPN and 247 Sports -- and he picked the Cyclones over Oklahoma and other big-name schools.You just see his film, and each game gets better and better and better, Campbell said. Hes got really good technique. He plays with relentless effort.Eaton started at Temple before getting injured and receiving a medical redshirt. He left the Owls after barely seeing the field in 2015, but last season at Pearl River Community College in Mississippi he caught 37 passes for 392 yards.Eaton will have to work hard to see playing time though. Big 12 first-team receiver Allen Lazard and Trever Ryen are returning for their senior seasons, and youngsters Deshaunte Thomas, Carson Epps and Hakeem Butler all showed plenty of promise in 2015.To be able to hit on all three guys was incredible, Campbell said.---More college football at www.collegefootball.ap.orgChad Thomas Jersey .

INDIANAPOLIS -- Michael Andretti smiles like a kid when you ask whats different in 2013. Hes not giving away the trade secrets that have turned his team from competitive in 2012 to dominant so far in 2013. He just wants to savour the moment and keep chugging along. "I just think were getting more experience, more confidence all the time," Andretti said after another successful practice at Indianapolis Motor Speedway. "When you get more experience and get more confidence, you get better results." Andrettis team wasnt exactly a pushover before. Last year, Ryan Hunter-Reay won four times and dethroned three-time defending series champion Dario Franchitti, James Hinchcliffe had five top-five finishes in 15 starts in Dania Patricks old car and Marco, Michaels son, closed out the season with three top-10s in the last seven races. Andretti Autosport saw those results as a good start. This season, those same drivers have combined to win three of the first four IndyCar races and take three of the top six spots in the points standings, and they have simply dominated the early practice rounds at Indy. On Sunday, the five Andretti Autosport drivers hoping to qualify for the May 26 race posted fast laps that ranked among the six fastest. On Tuesday, during the busiest practice session yet, Hinchcliffe grabbed the top spot early in the day with a fast lap of 224. 210 mph. What exactly changed during the off-season? Michael made some personnel moves that he declined to talk about, Hinchcliffe had a full off-season to work with his team and Marco went to work with a driving coach to shore up his skills on road and street courses. The payoff has been nothing short of remarkable for a team with two 500 titles and three points championships under Michaels stewardship. Marco said his coach told him he was relying primarily on his natural talent -- and it was causing him problems he could have avoided. "I learned how to fight and I learned some fundamental things about how to drive on streets. The biggest thing was I learned how to fight," Marco saaid.dddddddddddd Hinchcliffe has earned the first two wins of his career and will be one of the favourites for the May 26 Indianapolis 500. Heavyweight owners Roger Penske and Chip Gansassi are still looking for their first wins of the season. The 26-year-old Andretti appears to have mastered those street and road course demons with two third-place finishes and two sevenths in four races -- none on ovals -- and is off to the best start of his career. Marco trails Japanese driver Takuma Sato by only 13 points at the top of the standings. Hunter-Reay is back in the title hunt, newcomer E.J. Viso is driving well and even the newest member of the team -- Colombias Carlos Munoz -- has excelled at Indy. The Firestone Indy Lights leader needed less than 12 hours of time on the Brickyard to go from untested rookie to the top speed of Sundays speed chart. "I still need to prove myself," Munoz said. "We have to continue to work on our practice checklist and figure out what is going to work best for the team." Thats not all. After Kurt Busch took Hunter-Reays car out for a test last week and turned laps at more than 219 mph, speculation swirled about the possibility of the 2004 Cup champion attempting "The Double" in one of Andrettis cars. It will have to wait till next year because Busch wants to run a couple of other IndyCar ovals before giving this tricky 2.5-mile track a whirl. The future looks bright, too, as Andretti grooms 18-year-old American Zach Veach for an IndyCar career. The budding star is eighth in points in the Lights series this season. With things going so well, the obvious question is whats next? The end of the Andretti Curse? At Andretti headquarters, there are always reasons for caution. "A lot can happen throughout the month," said Marco Andretti, who was the 500 runner-up in 2006 and still hasnt been to Victory Lane at the 2.5-mile Brickyard. "Its a very humbling business. As soon as you think things are going really well, you can roll out the next day and everythings different." ' ' '
