Rebuilding in dynasty mode looks too easy

I've watched several creator videos and showcased matchups and the game looks nice! That said, based on some creator videos (for example, Bordeaux's Sam Houston video) it looks like re-building teams in dynasty mode is way too easy. I'm concerned that a lack of challenge might water down the experience and affect replayability. To me, the two biggest issues contributing to dynasty seeming too easy were:

1) Coaches level up too fast - In Bordeaux's video he had max, or near max, level head coach and coordinators in year 5. These coaches gave powerful bonuses to the team that and seems to outpace CPU coaches.

2) User controlled teams had far too great team progression, especially compared to CPU teams. Again, using Bordeaux's video as an example, it looked like as long as the user had a decent recruiting class (not even top 20) they'd easily progress to be the top ovr rated team in just a few seasons. In the Sam Houston video Bordeaux had some solid recruiting classes but, in terms of ranking, they were all in the 30-60ish range. By year 5 though, he had the highest ovr rated team in the country. I understand that the coach can make a difference in regards to player progression but classes ranked 30-60 at a non power 5 school shouldn't result in the strongest ovr roster. The power 5 schools who were landing top 20 recruiting classes should have had a higher ovr. In the video it looked WAY too easy to build a powerhouse team in just a few years.

Does what we've seen in these creator dynasties accurately reflect what will be released tomorrow? If not, and dynasty rebuilds seem too easy, would this be changed/patched at a later date?
