Well, if you're just looking for something to kick around and have fun with, I have a feeling based on whispers & opinions (meaning gossip: nothing factual, nothing in motion) that the "catalyst" of next year's Silly Season could be the 88 (just like one of the big catalysts last season was the 78). If they decide to replace Bowman (big if), I think they will most likely throw money at a more seasoned replacement to try and get that program back on track which could potentially lead to some dominoes. Or, they could throw money at a very proven youngster like Bell, which might trigger events at JGR to keep him, also more dominoes. So if you're looking to discuss/debate/predict etc, I would start with the 88, and the series of events that might happen should they decide to replace Bowman (again, important to stress, I have no knowledge of any changes being made to the 88 other than people talking about how badly things need to change there, which, I think would be fairly obvious to any casual observer).
Obviously I guess you could also start with where Bell goes, but I could see a situation where Toyota tries to strengthen Leavine for him or Jones or Hamlin or something, or convert another team for another seat or two. I think that will likely all take care of itself. Starting with the 88 seems like more fun.
Will also be interesting to see what happens at SHR if Custer keeps racing the way he's been racing. Though I could see Harvick doing one more season next year before being replaced by him.
