Splitting w/ the Saints would require the Saints to lose to either to the Rams or the Bucs for Carolina to win the Division. Assuming a split, Carolina could lose to the Jets (but not the Falcons) and still win the division if the Saints' loss is against the Bucs. If Saints loss is against Rams, then Carolina has to beat Jets/ Falcons.
Carolina only needs two wins to guarantee a WC spot so even if we get swept by the Saints beating Jets/Falcons gets us in.
I don't know about Beason but the Panthers were in base 4-3 on less than 1/2 of all defensive snaps last year. Obviously they want him on the field for those plays but the reality is that the Panthers play with only 2 LBs on the field most of the time (source: Football Outsiders). Losing him is losing a situational player not an every down guy.
The book Cam mentions is a self-help about interpersonal skills, effective leadership, and personal development. Regardless of the effectiveness of the book, I'm impressed that Cam is working hard at improving himself as a person and not just as a football player.
