NBC's Inexplicable Tennis Coverage

I knew today's NBC coverage would be a Williams sister-fest, but with Venus only on court for about a half hour before Anna Ivanovic retired with a knee injury, NBC scrambled and made a hash of its programming. First they showed the last 15 minutes of Federer/Soderling, which had already been broadcast on ESPN, then Venus/Anna on tape delay. When Anna hurt her knee, they covered the entire injury timeout without interruption. Now I like watching Anna get a massage as much as anyone, but why would you cut short match coverage to show an injury timeout?

But wait, it gets more bizzare. After showing Serena's quick thrashing of Hantchukova- which had also already been broadcast on ESPN- NBC then began to show us, get this, a lengthy RAIN DELAY on TAPE DELAY! So while there WAS live tennis going on, NBC showed us TAPED COVERAGE of the delay- including full coverage of Wimbledon's new roof opening and closing. Then they showed us play between Safina and Mauresmo when it finallyl resumed, and even showed us- on tape delay- their warmup! This rather than LIVE coverage of close matches involving Hewitt and Karlovic. Meanwhile, over on ESPN they were ahead in the Safina/Mauresmo match, so anyone flipping around would have already seen what NBC was showing.

Now I can understand the logic of showing us tennis on tape delay, but showing us rain delays, injury timeouts, warmups, and previously broadcast matches on tape delay? Give me a freaking break NBC. Please leave tennis coverage to someone else.
