To make sure I made my point, even though it favored the pack, I think the ref botched the Shiancoe TD, and chilly has every right to be upset about that.
However, calling a PI, hold, or whatever is a bang-bang, split-second decision that even then allows for some discretion of the official. That's really difficult, and I think the NFL and media/fan scrutiny tends to regulate the situation enough.
These guys get it right a lot - I never realized until I saw replay that Randy interfered on that bomb against Collins, or that Harvin had stepped out on his negated TD. Give these guys some credit, and let them be. As much as we've gripped about the officials lately, it seems that calls have evened out, and it hasn't affected the outcomes of games
