I know he's an offensive guy, but Coughlin's giant teams over the years have had a propensity for not only playing injured players too frequently, but more importantly, having a bad rotation on defense. For instance, Thomas, Webster, Phillips, and Rolle are out there 100% of the time. I'm pretty sure Boley is too. Other guys, Cofield, Tuck, Osi, Grant, etc are out there like 95% of the time, only a few plays off. In fact, I don't think we've rotated the linebackers at all this year. It's basically been the same three out there before Sintim went down, and even a four linebacker rotation is too little.
I know these are your defensive starters and stars, and maybe we don't have the best talent behind them, but you gotta give them a rest once in a while to keep them fresh, and so they don't wear down over the course of a season.
