IOWA CITY, Iowa -- After losing four senior starters, Iowa is in the midst of a major rebuild this season.The recent performances of its freshmen suggest that those efforts might not take very long.The Hawkeyes (5-5) have had serious struggles so far, most notably losing to Nebraska-Omaha at home. But that adversity has revealed reasons for optimism, because their freshmen have shown serious promise so far.Newcomers Cordell Pemsl, Isaiah Moss, Jordan Bohannon and Tyler Cook have all become major contributors. Pemsl, Moss and Bohannon started in last weeks upset of then-No. 25 Iowa State, and Cook (13.7 points, 5.3 rebounds per game) was a starter before a broken right finger set him back.Iowa plays Northern Iowa (5-4) on Saturday as part of an annual doubleheader in Des Moines.Getting them to understand how to prepare and how to work and how to put it together (is the challenge) because from the very beginning theyve been really good most of the time, Iowa coach Fran McCaffery said.The Hawkeyes were concerned about their interior play after center Adam Woodburys graduation. The 6-foot-8 Pemsl looks like he might be able to fix that problem.Pemsl was somewhat overlooked during the recruiting process because of shoulder and knee injuries. But he still led Dubuque (Wahlert) Iowa in scoring and rebounding in all four of his high school seasons -- and hes put up some impressive stats in his collegiate debut.Pemsl is one of just seven Division I players in the last 20 years to hit at least 75 percent of his shots in his first 10 games, which McCaffery said is a product of advanced shot selection. Pemsl (42 of 56 shooting) also averaging 17 points a game since taking the injured Cooks spot in the starting lineup, with 4.9 rebounds and roughly a block a game as well.Little things thatll help my game, help me get easy and efficient shots, Pemsl said when asked about his recent scoring binge. His teammates know that they can count on me to turn around and score or find them with a kick out.Bohannon is the youngest of four brothers to play Division I ball, including Zach (Wisconsin) and Matt (Northern Iowa).Although Bohannon was Iowas Mr. Basketball in 2016, he was expected to be Iowas backup point guard as a freshman. But like Pemsl, Bohannon jumped into the starting lineup four games ago and hasnt looked back, averaging over 13 points and 5.5 assists as a starter.Weve all prepared ourselves to be in the position we are in right now, Bohannon said of he and his fellow freshmen. Its hard as a freshman. Coach has been on me every day knowing I had to play right away.Moss, a 6-foot-5 guard who redshirted in 2015-16, had his breakout performance last week. He scored 35 points combined in wins over Stetson and the Cyclones to earn Big Ten freshman of the week honors.Hes got unlimited potential because very few people that are that quick and athletic have that kind of stroke, McCaffery said. Once he really believes hes as great as we think he should be, then hell become that great.McCaffery will have some serious shuffling to do when Cook, the most highly-touted recruit he ever brought to Iowa City, returns next week. And although the young Hawkeyes have had their moments so far, theyll much more likely to finish near .500 than near the top of the Big Ten.But the four seniors they lost led the program to three straight NCAA Tournaments. If Iowas newest core can continue to progress, they might someday match that feat.Youve got to be patient, McCaffery said.---More college basketball at www.collegebasketball.ap.orgJeremy Lin Raptors Jersey .

Dean Cosker, the left-arm spinner who was the last remaining active player of Glamorgans 1997 County Championship winning side, has announced his retirement after a 21-year career.Cosker made his Glamorgan debut in 1996 and then took 20 wickets in the trophy-winning campaign the following season. He reached as far as England A level in the late 1990s and remained a consistent performer, highlighted by the fact that his best first-class season came in 2010 when he claimed 51 wickets at 22.11, but he had not played a Championship match this season.He was also immensely valuable in white-ball cricket, enjoying his best T20 season in 2015 when he took 17 wickets. Overall in first-class cricket in finished with 597 wickets, 260 in List A and 100 in T20.Alongside his bowling he was renowned as an outstanding fielder, so much so that he was used by England as a substitute during the 2015 Ashes Test in Cardiff.I feel very humbled and privileged to have had the opportunity to represent Glamorgan over the past 21 years, said Cosker. I would like to thank all the coaches, players and particularly my family that have made this possible and who have continuously supported my career throughout.II have been very lucky to rub shoulders with some of the games finest players and characters, and both on the field and in the changing room I have been able to share some fantastic times that will stay with me as great memories for years to come.dddddddddddd.I have loved my time at Glamorgan and feel proud to say this was the only county I ever wanted to play for. Leaving the spin bowling department at Glamorgan in an exciting place has always been important to me and, with positive young spin bowlers at the club coming to the fore, I believe this is the case. I am really excited about the next chapter in my life and the challenges that it will bring.Hugh Morris, the Glamorgan chief executive, who was also part of the 1997 Championship-winning side, said: Dean has enjoyed a terrific career with Glamorgan and has been a great ambassador for the Club both on and off the field for more than 20 years.It was a pleasure to play with Dean at the beginning of his career and it has been great working with him over the last few years as a professional cricketer.
