First I would point out that a 7:30pm start in EDT is an advantage....hear me out:
You get a start that most people might still be tuned into college sports on the East Coast, plus less noise from other prominent matchups. Plus @4:30 p.m. PDT, you can watch and still go out to dinner or that cocktail party, kids school play or swingers party with your significant other on Saturday night after the game.
If the VATech game were on ESPN it might actually get a decent audience but....meh ACC network
So
As to the Berkeley/ 7:30 start in terms of desirability to watch in EDT in descending order.
1-North Carolina, this is an OK start time with the hype around Belichick circus, great time to shine for the bears
2 - - Minn, Big Ten matchup, midwest interest
3 -@OSU, meh...not great because of regional nature but first week so lots of pent up demand to watch all day and it will have eyeballs
Big Gap
3 @SDSU, nobody outside of California (fanbases) and CFB diehards are tuning into this one plus CBSsports, does anyone outside of the mountain west tune in to that?
IMO The biggest problem is ACC network, Last 8 Games are set for ACC broadcasts, is that set in stone?
