Players receive tweets from fans all the time. They get tweets from their own teams as well as opponents. Mike DeVito received one from a Patriots fan and don’t look into Mike’s answer more than just being nice, IMHO.
You could get upset that he laughed and said thanks about going to a team with less drama and more wins, but you know what. It is funny. Mike. We want you to stick around so don’t even think about joining the Jets who left for greener pastures.
