That multiple offers are filtering through should be some reassurance to Witten that this isn't now or never for his broadcast career.
Sure, they might hire someone at MNF who will be there many, many years. Then again, it might get back to how it was pre-Gruden, and it seemed new booth personnel were showing up with some regularity.
Total guess... maybe this second offer is from Fox for Thursday Night... I know it was said Buck/Aikman would not be expected to take that on, but I'm not aware that they've announced who would (?).
