Was Giglio chosen for the inauguration benediction in order to provide cover for Chuck Hagel?

"An evangelical pastor from Atlanta [Rev. Louie Giglio] announced Thursday that he would not give the benediction at President Obama’s swearing-in ceremony after a sermon he gave on homosexuality in the mid-1990s resurfaced earlier this week."

Suspicion: Giglio was chosen with full knowledge of that sermon and the intention that it would "resurface" and that he would then conspicuously withdraw. This would promote Obama's pro-gay stance and take the heat off Chuck Hagel, who's got an anti-gay remark in his record which the Obama people would like to submerge. It was all planned: the desire for Hagel to become Secretary of Defense, the known problem of his anti-gay remark, the desire to perform a conspicuous expiation, the identification of Giglio as a plausible benediction-giver with an anti-gay remark in his history, choosing Giglio, revealing the old Giglio sermon, Giglio bowing out in a tribute to Obama's rejection of homophobia, Hagel saved by the scapegoat.

I'm not saying I believe this is what happened, and I certainly have no inside knowledge. I'm just noticing the correlations and putting together a hypothesis. Please discuss.

You can pull me back from this suspicion if you make a great case for why else Giglio would have been chosen for this honor. He's a white male, by the way.
