My take (though not worth a lick o' Guinness or a whiff o' Jameson) is this: watching the play "live" on my 15", low-def analog CRT TV I thought he stepped on the line and out of bounds. I stepped away from the set to refresh whichever glass I was drinking from at the time.
I was (most pleasantly) surprised on my return to find that the call on the field was that he had stayed in bounds and scored a touchdown. I figured that a second, and possibly a third, official would have stepped in to overrule that call.
Replays from differing angles didn't change my initial opinion. They were ambiguous – no conclusive evidence. It just made me wish I'd wasted a shit-load of money on a 60" HDTV and HD cable package/energy sucking "box" to feed it. I'd have celebrated with every Domer Homer out there had the been upheld, but it came as little surprise that it was reversed.
Back in The Day (OK, OK – My Day) video replay didn't exist and the play would have been ruled a touchdown. Argument and controversy would ensue. Enter technology. Same old wine in a brand new bottle added to the cellar. Good or bad, game-changing or not; we've had challenges go both ways.
Until there are laser, pressure and GPS sensors, bar code scanners, algorithms and who knows what else installed in every field and attached to every part of each uniform that can be relied upon to supplant the instinct and "gut reactions" of coaches, players and officials; the human element remains.
Long live the human condition: "Rave on, it's a crazy feeling ..."
