I was satisfied with the LB situation as it was ,even if not exactly spectacular.
But much of the LB discussion is misdirected, IMHO.
If you look at the 2008 Defense statistic and eliminate the misleading red zone fluke statistics the real key to the Pats Defense is clear. The Pats were a Top ten Defense, The lowest statistic attributable to the front seven were the 15 th in the League rating against the Run.
Belichick penetrated to the heart issue and spent a second round draft pick, on Ron Brace to give Wilfork a legitimate NT relief to keep him fresh. No longer playing rookie ILBs will also help.
The Pats had devastating injuries to its its SS/LB hybrids. They lost Tank in the preseason after spending a considerable amount of time as an over-the-middle short coverage SS/LB. The Rodney went down too.
Once again, Belichick penetrated to the issue. He spent his first pick in the draft on a SS rover-back, who has played as a passing down LB, in Pat Chung. Now he has both Tank & Pat.
The improvement in the Run Defense will also transform the Pass Defense too. Instead of 3rd and 2 or 3, allowing a choice of pass or run, the opposition will more likely be facing 3rd and 5 or 6. These are obvious passing downs, and much less fearful about replacing a real LB with a SS/LB hybrid.
Lack of sacks is a partially misleading statistic. Seldom do sacks come on short yardage pass attempts. You need to force longer routes, to allow the pass rushers time to pass rush. You have to close off the short completion void, to have half a chance. And of course the Pass Rush produced only 31 sacks, better than more than half the teams in the League, and only 9 sacks from a good to great rating.
Belichick is a true Sherlock Holmes diagnosing the REAL problem.
