Really???? At the danger of math in public.....

I just looked at CAL system bid 14-02.

777 FO EWR: 93.9% (324/345) of the FOs can hold 737 CA EWR.....but didn't bid it.

777 FO IAH: 94.7% (90/95) of the FOs can hold 737 CA IAH.....but didn't bid it.

Of course on the 787 in IAH, 67% (102/152) of the FOs can hold 737 CA IAH. That's only 2/3 so you got me there.
