On March 1, 2007, the Dolphins offered Welker, a restricted free agent, a second-round tender (the second-lowest tender) of $1.35 million for a one-year contract. The Patriots, who were interested in Welker, had originally considered signing Welker, a restricted free agent, to an offer sheet which Miami would have had seven days to match; according to The Boston Globe, that sheet would have contained a poison pill provision which would have made the offer difficult for the Dolphins to match.[6] Ultimately, however, the Patriots decided not to use such an offer, and traded the Dolphins their 2007 second- and seventh-round draft picks for Welker.
Don’t confuse him with facts! ;^)
Welker wasn't worth a "good deal" at the time. He was small time and wanted out of Miami, the Patriots got him at a bargain. Moss was also a relative bargain because of his history.
But thanks for making my point. It's also proof-positive (be it Welker, Moss or Brady for that matter) that the 1st round draft choice penalty for cheating leveled against the Pats was a joke.
