"Rebuilding" is tearing it down and starting over and over and over again. You don't want to get into a cycle of tearing down and rebuilding over and over. That's what happens with the Browns, the Bills, the Lions (until the last two or three years), and other franchises that have losing cultures.
"Retooling" is different and it's something that good franchises have to do all the time, especially if they have a down year like we are this year. "Retooling" entails keeping what works and bolstering the rest. For us, we need a new coach and given that we've lost so many games by 7 points or less, it's mostly a coaching problem. Obviously, as I've said before, depth matters too.
Hit on a coach, bolster the depth, and we'll be ready to rock n' roll.
