maybe you need a chalkboard and some apples and orange graphics to understand my point. So let me help you out, the only thing that it means is that:
1. Moore is not a BAD draft pick, a 1std rounder that was the 32nd ranked starting LT in the League would be a bad pick
2. Moore, as a late 4th rounder, has a 15% odds to start in the NFL. He beat those odds even if he is in the bottom of the ranks, even if we don't like his play.
3. I don't want Moore starting, that doesn't mean he is a bad pick, as a late 4th, being a backup that can spot start is decent value and in a rookie contract he is worth more to the team as he is cheap depth.
Hope you get my point and can move on from your high expectations for a late 4th rounder at the 2nd toughest starting position according to draft position
