Yersinia pestis is extraordinarily virulent, even when compared with closely related bacteria. This is because it's a mutant variety, handicapped both by not being able to survive outside the animals it infects and by an inability to penetrate and hide in its host's body cells. To compensate, Y. pestis needs strength in numbers and the ability to disable its victim's immune system. It does this by injecting toxins into defense cells such as macrophages that are tasked with detecting bacterial infections. Once these cells are knocked out, the bacteria can multiply unhindered.
Not sure anyone is still reading this but I am wondering if anyone has looked at truncating some of these stats to only he first half or 3/4 of a game or until the score differential is >10 or something so that arguments of skewed data from changes in the gameplan cannot be used. One could also find ways of subtracting out ‘irrelevant’ data when the season was not in contention for a team or looking only at ‘critical’ game windows where an interception or sack would have been more critical. These kinds of data may be far more revealing of correlations to wins.
The Texas portion of the reserve had been land that few white men had wanted to cross, much less own, but it had also been state land, outside the control of the . government. Within two years the government reneged on the treaty, obtained the signatures of Comanche and Kiowa leaders on the new Treaty of Medicine Lodge Creek, and reduced the reserve to only six per cent of its original size. All that remained was a corner of the designated "Indian Territory." The substantial portion of the bison range that would at least in theory have been off limits to whites was left open to the commercial slaughter that touched off the Red River War of 1874-1875.
