Well, that's probably deceptive, as those guys are probably exceptional in other ways (publications as an undergrad, other research, etc) which takes away from their grades, or they only cared about certain classes which were important to their field.
My GPA looks "low" around a 3.3 cumulative (I have lots of C's in things I deemed unimportant) but I have a relatively high CS GPA (3.8-3.9), took many graduate classes during undergrad, worked at startups, consulted, did multiple years of research resulting in two publications with 2-3 more in the pipeline, worked on open source, gave talks at workshops and software engineering conferences, TAed, constructed two student led courses, etc.
It seems the most important thing is to demonstrate your ability to work as a researcher (your primary role as a CS graduate student) trumps all in graduate admissions, but that is just my 2 cents.
If you want to, you can take a chance on a player. If he's not good enough, he's still got your stamp of approval, so he can be sold at a higher price anyway.
