I'll add some thoughts here, take it as you want. Louisville will make a push for Jeff, we all know this. What the average Louisville fan doesn't see is the environment the Brohm family has created just a few hours north within the entire school and community (including Tyler Trents family). Here are some items to keep in mind-the Big Ten is a better conference top to bottom with the Big West (Purdue's) division having the easier path to the conference championship each year. (Iowa/Northwester/Wisky) With the way recruiting is going, Purdue could possibly own this division the next 3-4 years and everyone knows this.
Secondly, he's in the midwest at a Power 5 school winning, and recruiting well in just year 2. I also have a few connections at Purdue that are very close to the situation and can tell you the Brohms absolutely love Purdue, including his kids. Anything saying this is a done deal, is just local Louisville media talking out their rear. The other item that hasn't been brought up very much is Bobby and Jeff are very close, with Bobby essentially being his mentor. Coming him to replace him after being fired won't jive with the Brohm family-and the core values as he cherishes family-and friends. Tyra will have to tap dance here.
Purdue will be match or beat any offer financially proposed to Jeff, and they have the funds to do it (thank you BIG TV revenue). How high can Louisville go if this becomes a bidding war (not only with Purdue), not sure it will come to that but you guys can't afford 6M or more a year long term with given your financial situation. That would be a stretch realistically. Just my 2 cents, December should be interesting.
