One of the SEC’s oldest rivalries is renewed Saturday in Tuscaloosa, Ala. when Mississippi State visits No. 2 Alabama.The Crimson Tide (5-0, 5-0 SEC) have dominated the overall series between the two teams, going 82-18 with three ties. The last Bulldogs win against Alabama was at home, 17-12 in November 2007.To make it a more daunting task for Mississippi State — which has lost three straight after an upset of LSU to open the season — players are either entering the transfer portal or are opting out.Running back Kylin Hill, one of the Bulldogs’ top performers last season, is set to opt out this week and focus on the NFL Draft, according to a report in AL.com. That’s in addition to three other players reportedly headed for the transfer portal, including backup running back Kareem Walker, a senior.The Bulldogs (1-3, 1-3) were flying high with head coach Mike Leach’s Air Raid offense that dropped 44 points on LSU on Sept. 26. But since then, the Bulldogs have managed no more than 14 points in any game, and didn’t score on offense on Oct. 10 at Kentucky in a 24-2 loss.The quarterback competition is now open, with senior transfer K.J. Costello trying to hold on to the job and freshman Will Rogers trying to win it.”Both guys have performed well in practice. I don’t really like splitting reps with quarterbacks. I like to settle on one,” Leach said. “I would prefer that approach, but we’ve been awfully up and down. We need to figure out who gives us the best spark.”Alabama has scored 35 or more points in 18 straight games, and is the SEC’s top offense at 566.4 yards per game. Mississippi State leads the SEC in total defense, allowing 295.5 yards per game.The Crimson Tide have defeated 94 consecutive unranked teams under head coach Nick Saban, the longest streak in FBS history. Alabama is also 48-2 in October games with Saban at the helm.
