I guess I would ask, who did they "overpay"? Here's the list:
$50M+ Contracts:
Dez - Worth the $$$
Romo - Could argue injury history, but that would be using hindsight
T. Smith - Steal of a deal
T. Fred - Worth every cent
Carr - overpaid, but in last year of deal (also took a pay cut this year)
$20M+
T. Crawford - arguably overpaid, but still early in the deal to declare with any certainty
Baily -There's a reason they call him "Money" (well, two reasons if you consider his contract)
Zeke - Rookie contracts are pretty much predetermined -- he'll be worth every penny, and then some
S. Lee - Worth the cost, IMO, but could argue otherwise based on injury history
Witt - Worth his contract...he's getting up there in years, but he's still one of the team's main cogs.
Just looking at the list, there are a couple you could argue were overpaid, but that would be with the benefit of hindsight. The majority of names on that list deserved the contracts they got...especially if you consider the cost of not signing them, IMO.
