Dont pretend to know dick about soccer...But I saw that Rovers have the best away goal differential of any team of the top 5 leagues in English Soccer.I have read that they are going to miss a few good players today but the value cant be beat with them at over +220 now..They just played Oldham, so would think they know they can beat em..
FA Cup is sometimes a different animal. Players get rotated in and out and is usually not their best team on the pitch. I usually stay away from cup matches.
