The US international now has the respect of his team-mates having impressed in pre-season.
He said: "In the first pre-season game I did fairly well and I think I proved to the guys that this American kid can play.
"They had see me train, but that's different from a game-type of environment and they wanted to see me play.
"Some of the guys came up to me after that game and said I had passed the test. I said I appreciated that."
