I really don't blame Donovan for not knowing the rules. Although I do believe he scapegoated the situation with his ignorance (and then was stupid to publicly comment on it!) I do think players shouldn't bear the burden of knowing every nuance of the game. HOWEVER, the coaches are. I think McNabb shouldn't have gotten flack, Andy Reid should have. Judging by the multiple flags on non challengable calls that he made vs. the Ravens, the guy has no clue what is going on.
