I found video of a blocked FG and XP against the Seahawks and also a blocked FG against the Colts. On all three the right side of the line just got blown up and the kicks were easily blocked. Certainly can't fault Gano for those, and if it was that bad 3 times, it likely was that bad 3 more.
Doesn't Houston have 2 good kickers? Anyone remember if Shayne Graham could kick at Heinz?
