The lack of seeing the safeties is why so many Bears fans were down on Charles Tillman for years. I can't tell you how often I tried to explain why Tillman wasn't at fault for a lot of plays where, on TV, it looked like he blew his coverage because you couldn't see how the safety had bit on an inside route and left his zone wide open. When Tillman would let his guy go to where the safety should have been, the safety wasn't there. Tillman, being an amazing corner, would scramble to make up for the fact and then look like he had gotten beat, when in truth, he made an amazing play half the damn time preventing a touchdown.
I had this debate more times than I can count with "armchair experts" over the years, and it's only over the last two years or so that a few of them have said things like "Wow, I see what you've saying about Tillman all of these years!". To which I say, "Now you're seeing it because our safety play has improved enough so he doesn't have to do two jobs on the field anymore. When he's just doing his own job, he's all-pro".
The one time I had second level, 50-yard line seats for a Bears game was by far the best watching experience I've ever had because I had a good all-22 view. Usually I have terrible seats, and I miss a lot more than I would on TV, especially with the line play. That's why unless my seats are near the 50-yard line and somewhat elevated, I prefer to watch the games on TV. The various angles of the replays allow me the ability to look over who was doing what most of the time, but it still leaves a lot to be desired. What was cool about the seats I had on the 50, was that there was also a TV right in front of me where I could catch the replays for closer views. If I could watch every game like that, I would.
