Nico Rosberg was delighted to see Mercedes bring real innovation to the floor of the W07 on the second day of pre-season testing in Barcelona.The Germans car was the subject of attention up and down the pitlane as the team debuted teeth-like barge boards.We have a real innovation on the floor, it looks quite futuristic and we are excited about that, Rosberg told Sky Sports News HQ. It is important for us to be innovative and be one step ahead of the others because it is easy to copy afterwards, so when they see things on our car they will copy them and automatically go faster. So we have to stay one step ahead. In all Rosberg completed a mammoth 172 laps of the Circuit de Catalunya, equating to nearly 500 miles as Mercedes showed incredible reliability once again. Team-mate Lewis Hamilton had completed 156 laps on Day One. The Spanish GP consists of only 66 laps.It was a great day, I was excited to get back in the car again. It was good, it was a real Formula 1 marathon today, lots and lots of laps and kilometres, he added.That is what we need to do, we need to push the car to the limit to find little problems on the car because at some point something will break. For now nothing has broken, so we need to keep on going, do lots of laps and see where the weak points are. So that is quite successful at the moment. Ferrari have taken the headlines by topping the opening two days of testing, but there is no panic at Mercedes.Lap time-wise it is not realistic where we are, we havent shown are cards yet and are still holding back, Rosberg said.For sure the car is quick, the opposition also seem to be quick so how quick we are nobody knows for now, but of course we are confident.

Thats about all he can do right now, so hes trying not to think about when he might be able to play again for the Los Angeles Lakers.LINCOLN, Neb. -- When No. 7 Nebraska visits No. 11 Wisconsin on Saturday night, it will have been 23 months since DeMornay Pierson-El returned a punt for a touchdown and two days shy of one year since he sustained a devastating leg injury.Anyone in the Cornhuskers scarlet and cream would love the high-stakes game at Camp Randall Stadium to be the stage where Pierson-El shows that he is all the way back.Im getting into my groove, he said, and everybodys starting to see it.The first sign was in the third game, when he broke a 45-yard return to set up a momentum-shifting touchdown against Oregon. Two weeks later, the junior from Alexandria, Virginia, busted a 27-yarder against Illinois for the 11th return of 25 yards or longer in his career. He was one missed block from going all the way on a return against Indiana, and last week he scored his first touchdown of the season on a 40-yard catch-and-run against Purdue.Hes capable of, just like that, in the blink of an eye, making a big play, coach Mike Riley said, and so Im really happy for him personally to come back from two major injuries a year ago.Pierson-El emerged in 2014 as one of the nations most dynamic playmakers. He ran back three punts for touchdowns, had almost 200 more yards than anybody in total punt return yards and his 17.5-yard average ranked second. As a receiver, 17 of his 23 catches came in the final four games, and he set a school bowl record with eight receptions against Southern California.Upon his hiring, Riley excitedly spoke about the ways Pierson-El could be featured in his offense and as a return man in 2015. But Pierson-El broke his right foot in preseason practice and missed the first four games. In the Oct. 31 loss at Purdue, he tore two major ligaments in his left knee, ruptured his hamsttring and fractured the leg, all while celebrating a teammates touchdown.ddddddddddddierson-El went into this season having mostly recovered physically, but he lacked confidence in his left leg. He thought sitting out as a redshirt. In retrospect, he said, doing that would have been heartbreaking.Im absolutely glad Im playing, Pierson-El said. It was a decision that I didnt know where it was going to go at first.Against Oregon, he fumbled while making a fair catch, and he lost yards on a jet sweep. Any doubts he might have had about playing this season were erased late in the half when he sidestepped a player and went 45 yards deep into Ducks territory.It was positive thinking all the way, he said. My teammates have believed in me. The trainers have put work in day in and day out. A lot of people dont see that. Its a weight off the shoulders because Ive been waiting for it. I knew what I had to do, which is catch it and just run.Pierson-El did plenty of catching and running as a freshman. His 596 punt return yards ranked third on the school single-season chart, and he tied for the national lead with three returns for TDs -- 86 yards against Fresno State, 62 yards against Michigan State and 80 yards against Iowa.This season, his 9.9-yard average on 11 returns ranks second in the Big Ten behind Michigans Jabrill Peppers. Pierson-El said hes doing nothing different this week to prepare for Wisconsin, which is giving up 6 yards a return since Akron broke a 55-yarder for a touchdown in the Badgers second game.His goal in Madison?Hopefully get into the end zone again, he said.---Online:AP college football website: http://collegefootball.ap.org ' ' '
