Those are the exact same running backs I have to decide between, and I'm going BJGE and Sproles. If this were the regular season and BJGE was continuing to underperform I might have taken a chance on Wilson, but it's the playoffs, BJGE is on a streak of good games, and Sproles is coming off of a monster game into a good matchup (for receivers, which is what Sproles basically is). While Wilson's matchup is amazing and he has the talent to put up a huge game, he could also fumble on his second carry of the night and Coughlin could bench him like he did in the first game of the season. I'd only risk starting Wilson if my other options were sketchy at best (like Bryce Brown, who still has a half to redeem himself).
I do play in a .5 PPR though, so I value Sproles a bit higher than I would in a standard league. I think I'd still start Sproles in a standard league, but I'd at least be considering Wilson.
Yeah, I went with BJGE and Sproles. I think Wilson is a case of the hype machine and I like both BJGE and Sproles matchups this week.
