I think it's the opposite - the train is just leaving the station.
This team isn't the culmination of years and years of stellar recruiting. It's a couple of good-to-very-good recruiting classes and some nice Portal additions patched together to form a good football team.
It only gets better from here - we don't have anything like the depth of quality Cristobal wants. The drop off on the Dline is stark, for example, and the secondary is nowhere near as good as it could / should be.
Essentially the only room that looks anything like it will do in the future is the RB room, where we have 6 quality P5 players / starters.
