I highly doubt they would have taken Eli out if he was playing well in the first half. Yes, that would been "taking a dump on a legend" as 05 says, and also too obvious a tactic to lose the game on purpose.
All that we know for sure is that Eli didn't want to start and (very likely) get taken out of the game.
