In short, a serious AFFIRMATIVE to Adalius Thomas but a serious NEGATIVE to Wes Welker. Adalius Thomas is worth the money but Wes Welker is not worth the offer reported by Adam Shefter of NFL.com:

"The Patriots plan to sign Miami restricted free-agent wide receiver Wes Welker to a seven-year offers sheet worth $38.5 million. Once Welker signs the offer sheet, the Dolphins will have seven days to match it. If they decide not to, they would get the Patriots' second-round draft pick."
