There's really no great insight here or talk about where this game might lead. The Eagles have shot themselves in the foot by losing two consecutive ACC games to lose their national title hopes and put their ACC championship in jeopardy. Now it comes down to this game. If the Eagles win this game they win the Atlantic Division of the ACC and will be going to play the coastal division champion (The winner of the final game of the season between Virginia Tech and Virginia) in the ACC Championship game. If they lose, Clemson will go instead and BC can look forward to another irrelevant non-BCS bowl where they'll likely be passed over for worse teams with more reputable programs like Miami and Florida State.
Matty Ice has successfully played himself well out of Heisman contention. When he came back after a terrible game to win in Virginia Tech he was scrappy. When he just played badly against Maryland and Florida State he was just bad. That's three bad games in a row for Ryan, it might be a gambler's fallacy, but I think he's due to get his act together.
BC's defense has been equally lackluster after being impressive all year. They allowed more points to Maryland this week than the Terps had scored against any opponent this year with 42. By comparison, the Terps scored only 31 against I-AA Villanova and 26 against Florida International, the team with the longest losing streak in I-A football and currently 0-9 this season. The Terps were also on a losing streak in which they scored under 20 points in 3 consecutive games and lost to the UNC Tarheels. Maryland QB Chris "Goldilocks" Turner had a career game to put Maryland over the top.
Clemson, on the other hand, is currently on a four game winning streak and is now actually ranked above Boston College in the rankings at #15. Clemson QB Cullen Harper has put up some strong numbers this year. BC will have to find the winning formula and remember how to get temporary amnesia in order to beat the Tigers and earn the right to represent the Atlantic Division.
