I would have to say that DeZ not getting into trouble last season does not add value. It simply doesn't decrease value. Paying someone extra not to act like a jackass is someone counter productive.
Fair enough... do you disagree that his stats add value? His lack of trouble off-the-field was merely one of the "facts" I created in my hypothetical.
As far a "value" is concerned, the question shall always be, is Dez'a future performance and productivity going to be proportional to his contract and his contribution to the team when compared to his teammates and their contracts?
Yes, I understand how you have to weigh a player's value to the team when negotiating a contract, and you have to weigh the impact for the rest of the roster.
But in a general sense, when people claim that Dez's production will be replaced easily enough, and act like the team will win without him, that's minimizing his value to the team.
Due to the salary cap, whenever we increase someone's value via a new contract then we are also devaluing someone else. There are only so many dollars to go around.
You're not devaluing other players when another player's value increases. If the player becomes too valuable for the team to afford, then the team simply lets said player go... at least in a true free market.
For instance, Dez's value increased throughout last season due to his play... And so did Murray's. The team realized that they couldn't afford to pay both at the value the players commanded. But the increased value to Dez didn't devalue Murray. Murray realized his true value through free agency.
But when the term "devalue" came up in this thread, it was meant as a synonym for "minimizing impact to the team." Murray's impact to the team was huge last season. However, when it came time to pay him his money, the team weighed the pros and cons... they likely considered the high workload of 2014, his injury history, his fumbling issues last year, the likelihood that his production could be replaced by other players. Those things (facts) likely devalued him (or minimized his importance to the team) in their eyes.
The same thing is going on here when people talk about other 1000 yard WRs this team has had, the optimism for the potential of the other WRs currently on the roster... And we all know Dez is going to be here for 2015 and probably 2016 at least. It's like they are preparing themselves for life without Dez, even though we don't really know when that is going to happen.
