Mike Sando: The 49ers did accuse the Jets of tampering with Crabtree during the negotiations, but the timing of these transactions is probably a coincidence. NFL rules would prohibit the 49ers from trading Crabtree's rights before March. The Jets acquired Edwards with the 2009 season in mind.
Also, it's pretty clear those tampering charges would have made it impossible for the Jets to show any sort of interest in Crabtree now or in the future. For that reason, the Jets would not have been waiting to see what happened with Crabtree before deciding to pursue a deal with Edwards.
