If the price is low enough on a one-year make-good deal, I'd be happy to try him out. With his legs at 80% or better, Peterson's field vision and cutting are world-class. I agree there is no way he gets an 8-figure deal; probably not even 8 figures of guarantees.
His off-field issues bother me far less than other players for whom that's a concern. There are cultures within the US where his behavior is absolutely the norm and acceptable - and not, like, cults, I'm talking about a majority or
near-majority of the population in some areas. ~20 states allow teachers to do spanking in school (with parents' permission), though obviously not to Peterson's degree. I'm a parent and wouldn't discipline my kids that way, but he did it out of love not psychopathy, he pled no contest and did his community service, and has expressed remorse and says he wouldn't do it again. I have way more emotional willingness to say he's learned his lesson than I do for, say, wife-beaters. This isn't Ray Rice, much less the Eagles running Michael Vick out there for 5 years.
