Of the two, Swigert seems like the more likely guy to get a 6th year. In fact it is sort of implied in Addazio's update on Monday.
Bobby Swigert is really doing well. We have to see if it's this season or next. He looks great & he is starting to get confidence. - Addazio
To me, the "this season or next" means that BC knows Swigert will get a 6th year. Based on his numerous infections and setbacks, I could understand why. All the issues essentially relate back to the initial injury (one of the NCAA's loose criteria). I hope Bobby waits. We are not a pass heavy team this year, so I don't know if he would have much of an impact. Next year he could be featured from the beginning of the season and could potentially play in all 12 games.

Harris Williams' case won't be rubber stamped by the NCAA. He only played one game this year, but he redshirted as a true freshman. Like Momah, the NCAA could very well rule that decision was elective. Even if BC comes up with something to explain that first redshirt, I don't know if the NCAA will care. Like Swigert, Williams might be even more valuable next year when so much of the line turnsover.
We won't know anything officially until after the season is over. The best aspect of all of this is that both guys have their degrees and BC is playing well without them. Let's hope they play again though because both have earned a better ending than the one they've had.
