The attrition plays a big part. But Dooley recruited ok his first year (Stone, Fulton, James - all in the league), his second year gave us Tiny. It was the slow (for some) realization that Dooley was not anywhere near the coach/leader we needed that led to the disastrous 2012 class of zero lineman and virtually no elite talent (apologies to Randolph).
The expectations for Jones will be there this season. All Dooley guys are gone. Jones' guys are upperclassmen. The team is deep and experienced. No excuse not to be a great football team.
