Just thinking aloud, I'm curious to see if Newman continues to race after this season.
Chastain would be a great replacement, but if John Hunter continues with the strong finishes. I could see him move into the 6 car with Buescher in the 17. Newman is a tough SOB, I think more than likely he continues to race out his deal with Roush.
Other than that, I don't see a lot of movement happening after this year. One thing I would like to see is Brett Moffitt move to Our Motorsports, if they procure more sponsorship, on a full-time basis. I for one would not mind Moffitt to be a full-time truck driver, but at the age of 27, I'd like to see him give Xfinity a full-time go and eventually move to Cup for another shot.
Bowyer I think is out of the 14 after this season, he'd have to win about two to three races to keep his seat at this point. Briscoe would be a natural hand and fit in the 14, but I'm still concerned for Stewart-Haas after Harvick decides to hang up his helmet. The team needs to find an eventual replacement for him sooner than later IMO.
Keselowski is still in the air. Matt D has been performing well and if he continues to do so, I don't see how they move him out of the 21. Cindric will be ready for Cup, but who is he going to replace? Cindric could move to the 21 and Matt D to the 2, but its far too early to tell. Keselowski is the only guy who does not have a contract for next season out of the three primary Penske drivers atm.
Once again, just thinking aloud over some possible changes.
