Adrian Peterson - "It would be nice," to come to Dallas. "I've got family here, my dad's here. But I'm under contract, so we'll see." #NFL— Mike Leslie (@MikeLeslieWFAA) April 29, 2015
However, he is still under contract with the Vikings and they have no intention of trading him. Per USA Today:
“I think Coach (Mike) Zimmer stated it pretty clear that we have no interest in trading Adrian Peterson, and we don’t,” Spielman said.
“Adrian made a mistake. He’s paid the price for that mistake, but I think if our organization didn’t believe in Adrian Peterson he probably still wouldn’t be here today and that’s from our ownership on down.”
From a Patriots perspective, they'll face the Dallas Cowboys in Dallas in Week 5, which may or may not include Adrian Peterson. The Cowboys do need a replacement running back after star running back DeMarco Murray went to their NFC East rivals, the Eagles, so I'm sure they'll be monitoring Peterson closely.
