Samuel got his money. Its clearly debatable as to whether or not he deserved it.
Its also questionable as to how clutch Samuel's post season play is. One could say its not more clutch than that of Ty Poole's. Samuel blew 2 coverages, both of which eventually led to TDs by the Giants. And, on the same drive in which he blew a coverage, he dropped an interception that would have ended the game.
I happen to disagree with your assessment of how teams typically handle the opposing's #1 receiver. Most teams will put their #1 CB on the #1 receiver when the drop off between the #1 and #2 receiver is considerable. When an opposing team is like the Patriots and you can't do that, then, yes, opposing teams will put their #2 corner and a safety on the top receiver and put the #1 corner on the #2 receiver. Given that Hobbs was injured and the clear size advantage that Burress on a short route like that, it would make more sense to put Samuel on Burress and Hobbs on Tyree/Toomer?
Samuel wasn't on Burress because he can't handle the physicality of the opposing receivers and doesn't have the make-up speed that Hobbs does should he get bumped off.
