The wide receiver left the Ravens' AFC North rivals during the off-season to join the Miami Dolphins.
When asked about today's opponents, the 27-year-old told reporters: "Most definitely, I know they're my least favorite team. We have to beat those guys.
"First of all, they're the defending champs. So it would definitely be big for us to win this football game. If you think for one second, because they lost some players, that they're not going to come out and try to whip our butts, you got it wrong. These guys are still the Baltimore Ravens. They still have the same mentality."
The Ravens and the Dolphins both head into today's game on the back of defeats last weekend.
