The most obvious was the Dolphins being able to leave Pittsburgh with a 34-28 victory that kept them tied for sixth place in the AFC standings with the Baltimore Ravens.
Wallace also got to spend time after the game with former teammate and close friend Antonio Brown, with television cameras catching them exchanging jerseys.
Afterward, Wallace spoke to reporters in the Dolphins locker room. Here are some of Wallace's comments:
Describe your emotions today taking the field in a Dolphins uniform: "It was a little different but at the end of the day we knew we had business to take care of."
Describe the nice moment after the game with Antonio Brown and exchanging uniforms: "That’s my brother for life. We played together for three years. I have a lot of love for him and his family."
Take us through that play where you helped spring Daniel Thomas to a big gain: "He made a great play. I tried to get out in front and make a block on the last guy. Unfortunately for himself, he’s slow. [Smiles]"
What do you have to say to the Steelers fans in Pittsburgh?: "I had a great time while I was here. I love and respect everyone here. I will always have them in my heart for my whole life. Things happen for a reason. You aren’t always happy about things, but that’s life. You have to do certain things in life that are the best for yourself. I will have love for these guys forever."
