….Is that it has a poor track record for working in the past.
Mike Martz left the Rams mid season in 2005. In 2004, the Rams surrendered 50 sacks. In 2005 (the year Martz was coach for half the year) the rams surrendered 46 sacks. In 2006, the first year after Martz was gone, the rams surrendered 49 sacks.
Mike Martz left the Lions following the 2007 season. In 2007, the Lions surrendered 54 sacks. In 2008, the first year after Martz left, the Lions surrendered 52 sacks.
Mike Martz left the 49ers following the 2008 season. In 2008, the 49ers surrendered 55 sacks. In 2009, the 49ers surrendered 40 sacks, a marked improvement. However, closer examination shows that 32 of those sacks came in the first 8 games of the season, when Martz rather stubbornly stuck with J.T. O’sullivan at Qb. For the second 8 games, the 49ers started 2009 starter Shaun Hill, who was sacked only 23 times. Averaged over a full season, he would have been sacked a total of 46 times.
So, Martz has left three teams. Twice the difference in protection was negligible. The third time, it was debatable. In none of these instances did the team improve to anything that would be considered acceptable or even “average” (average sack rates hover around 29-30).
Again, I’m not saying that there will be NO effect to getting rid of Martz. I am saying that the track record isn’t really there to support the claim that it is ALL we should have had to do……
