Why would either come here? Why would this team somehow become SB contenders because of them? This team could have Vince himself and they're far from SB contenders..
1. Jim is already "here" coaching at UM and will be here for some time hopefully.
2. John and Jim are very close and John was obviously missing spending time with Jim, it came through loud and clear in the sideline interview how much he was enjoying the time and watching not only the game, but his brother coaching too.
It's a perfect time for him to switch as Ravens are having a down year. Lions do have good talent jjst really bad coaches. If Saints win vs beatable Cowboys who are without Romo and Dez and game is in NOLA, it is the Lions #1 overall pick to lose. If they get that pick, John could reset the team to a good extent while retaining the existing talent. It really would be a great situation for him.
