CONSPIRACY THEORY ALERT!
Could it really be that they may be planning something bigger/better? With HCDB turning around an anemic offense, energizing the fan base, a solid season (i.e. 6 or more wins and a bowl) and they may be thinking they can do better than a new roof and expanding the concourses - a new stadium is more feasible. When looking at the renovations and what a new stadium would cost, it may be better to suffer a few years more and save/invest in a better stadium. Perhaps, even Baseball!
OK, enough dreaming, back to our regularly scheduled doom and gloom. Remember, the sky may be falling, but it won't fall to far, we are NOT Rutgers.
