The revisionist history is that he was played out of position here. Baun was developed as an off ball LB to play either Mike or WIL which are very similar positions in our defense. But, he never beat out the guys in front of him. Because of that he was used a SLB on occasion and as a situational pass rusher to try to get him on the field. And fans complained that they were trying to convert a pass rusher to an off ball LB and that they didn't use him more as a pass rusher. There were huge numbers of posts calling him a bust and calling for him to be cut until last year. Even last year most people didn't care if he left in free agency. Not to be a kiss arse, but I think Andrus was one of the few that thought singing Baun to a new contract was a good idea.
Now that it has been shown that the Saints were right to convert him to an off ball LB, everyone is pretending that they always knew he was an off ball LB but the Saints used him wrong by using him as a pass rusher.
This is the true history of Baun. It sucks that we lost him after we developed him, but he just never beat out the guys in front of him here and he took less money to go to Philly because they had an opening for him to start and we didn't.
