Has Marbury Lost His Swagger?

Has Marbury Lost His Swagger?
Came across this article about Marbury in Newsday:

Marbury should be an effective player for the Celtics. He should give them more scoring off the bench, when Ray Allen needs a breather, and another penetrating guard for those drive-and-kicks that Rajon Rondo has mastered. But the most noticeable issue with Marbury is, after sitting out for over a year, his trademark first step isn’t what it used to be (and the second one is even less explosive). Perhaps more concerning for Rivers than anything Marbury is showing physically is what you see from him mentally. He looks like he’s trying too hard. Hesitating. Second-guessing.

I felt that Marbury was coming around. He had developed some chemistry with Eddie House and was starting to pile up the assists (averaging about 4.5 apg in his final six games).
The shot has not been there consistently. He’s just 1-6 from the field in the playoffs with a combined -19 +/-.
Maybe its rust, maybe its a problem establishing a rhythm off the bench. Your thoughts?
