Jeremy Lin has signed the Houston Rockets' new, renegotiated offer sheet. But, despite going to seemingly Herculean lengths, the Rockets haven't gotten it to Knicks GM Glen Grunwald yet, according to the Houston Chronicle's Jonathan Feigen.

The saga continues. The Rockets did not deliver the Lin offer sheet, after all. Imagining a PI in a trench coat staking out Tao.

The league had already made clear that the offer sheet needs to be delivered to Grunwald, not just sent to the Knicks' Madison Square Garden offices, which likely means that there is a hapless Rockets front office staffer looking all over Las Vegas — where many NBA personnel are for Summer League action — for him.

This all matters because the Knicks will apparently have three days from receipt of the offer sheet to match any deal, which they have indicated they will do, and they can certainly drag the affair out for all of those 72 hours if they want, forcing Houston to keep an iron in the fire that might distract from other offseason work, like ironing out a Dwight Howard trade.
