Trent Richardson is most likely moving on to the NFL draft, so Alabama will be looking for a new starting running back.Eddy Lacy is the front-runner for the job right now since he has played a good amount this year behind Richardson. Dee Hart is a redshirt freshmen and is recovering from a torn ACL suffered in spring practice. However, Hart is a small, speedy guy at 5’8″ and 190 lbs, so it might be hard for him to carry the ball 20-25 times a game while taking hits from SEC defenses.T.J. Yeldon is a big running back, listed at 6’2″ 205 lbs. He can run through the tackles and also beat you on the outside with his speed. Yeldon can catch the ball out of the backfield really well, as he as shown in high school while lining up at wide receiver sometimes.Yeldon ran the ball 232 times his senior year, racking up 2,193 yards and 31 touchdowns while leading his team to the state championship. Nick Saban is known for using a two-headed monster at running back, so expect Yeldon to come in right away to share carries with Lacy and be a contributor to the running game for the Tide. Alabama is losing many stars on the defensive side of the ball.The Tide are losing three cornerbacks,—Dre Kirkpatrick, Dequan Menzie and Phelon Jones—and they are also losing Mark Barron at strong safety.Starting free safety Robert Lester is undecided on whether or not he will leave for the NFL draft. If Lester does leave early, Alabama will have huge holes to fill in the secondary. Hasean Clinton-Dix and Vinnie Sunseri are two returning freshmen who played a little at safety, and they have shown potential.Landon Collins is a big-time recruit. Many recruiting experts have him ranked in the top 15 and as the top safety in the country.Collins is from Louisiana, but Saban stole him from the LSU Tigers. He has the size to play cornerback or safety in college, and he plays well in man coverage and zone coverage. Collins is not afraid of coming up in the box to stop the run; he plays physical and smart, so he is perfect for Saban’s system.Since Collins won’t be at spring practice, he will be behind in learning all of the schemes, so he might start the season on kick and punt coverages. However, he has too much talent to not make an early impact for this defense. Since Julio Jones went to the NFL draft, Alabama’s passing game has not been that effective. Marquis Maze has been the leading receiver, but opposing defenses still stack the box to stop the run.Alabama will be losing Maze and Darius Hanks, so Saban will be looking for two new starting receivers. Wide receiver is Alabama’s biggest need on the offensive side of the ball. DeAndrew White has shown he can play. He has the speed to stretch the field, and he can make some spectacular catches. I will be shocked if he does not start next year.Amari Cooper is rated as a top 10 receiver coming out of high school. He is 6’1″ and 175 lbs, but he needs to put on some muscle when he gets on campus. Cooper scored on a long TD pass in the Under Armor All-American game. He has good hands and speed to get behind defenders.A.J. McCarron needs more wide receivers to throw to, so Cooper should be in the lineup early. The linebackers for Alabama are what make their defense so good; they are all physical, smart and fast.Alabama is losing three linebackers this year, so it will be looking for replacements. Jerrel Harris is graduating, and Courtney Upshaw and Donta Hightower are headed to the NFL draft.Nico Johnson and C.J. Mosley are going to be the leaders of the defense. Trey Depreist will be a sophmore next year, and he should be fighting for a starting position since he showed he can play middle linebacker.Reggie Ragland is a beast. He is 6’4″, 250 lbs and has speed. People from Alabama are already comparing him to former Alabama linebacker Rolando McClain.Ragland can stop the run, get to the quarterback and make impact plays. He is so quick and strong that he is almost impossible to block. With Alabama losing a couple of linebackers, expect Ragland to make highlight plays as a freshman. Eddie Williams has the most upside on this list.Williams is listed at 6’4″ and 204 lbs, and he is surely going to put on more muscle in college. He can play wide receiver or safety, which gives him the best possibly to make an impact in 2012.If Williams plays safety, then he will look like a linebacker playing in the secondary. He will crush receivers trying to catch a ball over the middle, and he has enough speed to keep up with any receiver. Williams can also run up in the box and give a running back a big impact hit; the quarterback will always have to know where Williams is on the field.If Williams plays wide receiver, people say he will be the next Julio Jones.Williams will be hard to cover with his massive frame of body and speed. He will most likely start in the opening game against Michigan, and McCarron will love to have a big, tall receiver to throw to. Williams could line up opposite of fellow freshman Amari Cooper, and they could become a deadly duo for years to come.It’s not surprising that Alabama fans cannot wait to get Williams on campus, because whether he plays wide receiver or in secondary, he will step in right away and become a force in the SEC.
