So, where the roots are deeper, the grass is obviously healthier (probably thicker and taller as it is better nourished/water uptake) and where the roots are more shallow, the grass isn't as healthy, less capable of choking out the weeds, particularly the crabgrass.

Makes sense, it is why I grow/mow my grass tall and do everything I can to encourage deep root growth (increasing my OM, using Myco coated seed the last time I overseeded, using TTTF seed, etc.) and keep the grass as thick as possible.
