The Rams really need Aaron Donald if they are going to take steps towards improving on what was a disappointing first season in Los Angeles, and it seems as if they aren't making any progress towards getting him actually on the field by the start of the season.
This report states the two sides as so far removed from a possible contract agreement that Donald would be willing to miss the entire 2017/18 season in order to get what he wants.
That's something the Rams simply can't have happen, hence the reason for the report. We will keep you updated on this as more news becomes available.
