I am not saying anything new here, but if this is true, to me, this seems very short-sighted of the other owners. By striping the Patriots of draft picks, they are severing limiting the ability of the team to improve itself in the immediate future. The group that is most hurt by this action is not Kraft and the ownership. The group that is most hurt are the fans of the Patriots, or as I would call them, a significant portion of the NFL's customer base. I do concede that fans of other teams make up a larger portion of the NFL's customer base.
If this practice continues over the years, in the long term, the league's approach of alienating the fans of successful teams is going to piss off more and more of their customers.
Except the Jets fans because those fuckers will never be successful. May Woody Johnson live forever.
I think your question presumes a lot more long term thinking and maturity than the average NFL owner, or average person, normally demonstrates.
There are so many reasons why an owner would not let the "if it can happen to him, it can happen to me" type rationale drive him. Owners think that they wont be on the receiving end or ignore the risk because
- they don't think much past the present
- they believe that their team doesn't cheat so nothing bad like this is likely
- they believe in their own ability to control unexpected problems
- damn it, the Patriots are cheaters, so they deserve all that's coming
- damn it, they don't like Kraft for other reasons, so he deserves what he got
- damn it, they don't like the Pats winning all the time, so let's tie one hand behind their backs
