Nobody with a brain expected Levy and Jauron to fix this right away. They inherited a mess on offense and defense, but a quality special teams unit. They had holes everywhere. You had to know that this would be a two or three year effort.
Start plugging the holes one year, plug some more the second year and watch the first group mature. In the third year, you finish plugging the holes while the first two groups mature into solid players. There were that many holes to fill.
I think they're doing a pretty decent job on defense so far, and that seems to have been the focus this first year. We're still pretty lousy at stopping the run and stopping teams at the end of games, but it's still the first year of the plan and so far I'm not disappointed in the effort.
I think they might have underestimated the complete mess that is our offense, and I also think they ended up not getting their money's worth out of the stiffs they brought in for the line. Fowler will probably be serviceable, and Peters is decent, but beyond that we have, basically, nothing for a line.
I expect this offseason we will see a focus on bringing in some better quality offensive linemen in free agency and a focus on offensive and defensive linemen in the draft. But I wouldn't expect more than one big offensive lineman FA signing, which means we still are two good offensive linemen away from a decent line. Those we draft next year will need at least a year to develop. A lot depends on if Pennington (or Butler) can prove by the end of the year that they belong in the league, if not on the starting line.
Even if we focus 100% of our off-season efforts (FA and draft) on offensive linemen, we're still talking a couple of years to see that effort bear fruit. It sucks, but unfortunately that's the way it is, and we have to deal with it.
