Again, did you really expect the Saints to give the transition tag* to a backup linebacker, to force them to stay, in readiness for when DD did eventually fall off?
* Transition tag for LB = $19.98m
Reminder that the Saints offered Baun a deal. He chose to leave, I'm glad it worked out for him.
But this has all been covered before. This thread is like a dreadful merry-go-round of poor reading comprehension.
