Kelcy supposedly Bid $170 for TRGP before taking a run at WMB. Obviously everything has declined since then, but it was on his radar. TRGP covers their dividend and isn't heavily hedged ie Oil &NGL price increases go right to the bottom line. Export a lot of propane to Latin America
EPD could never buy WMB because of regulatory issues. They would have to divest a ton of assets to get it past regulators. To buy WMB, EPD would have to sell off large parts of it.
That's why EPD was never part of the original auction process.
