I agree with this. The 48 will be the best of the bunch, Chase will probably get a win or two, the 5 and 88 I don't see doing as much.
Even though an HMS driver won the championship, I'd say they were only the 3rd or 4th best team this year, definitely behind JGR/FRR and Penske, and probably on par or slightly worse than SHR. I hate to do the stick-n-ball thing again, but I'd equate Jimmie's championship to an NFL team that went 10-6 in the regular season but got hot in the playoffs and won the Super Bowl. In other words, a championship team that still has an issue or two to address for the coming season.
