Relationship between static, kinetic, and rolling friction coefficients

[JWest]

What is the relationship between static, kinetic, and rolling? Is static supposed to be less than kinetic and kinetic less than rolling? Can someone help me out?

If there's no friction, an object can't roll.

Static friction occurs when the object stops moving, i.e. when the force provided by friction cancels out the net-force.

Kinetic friction occurs when the object continues moving with decreasing acceleration due to friction until it eventually comes to rest.

What I'm asking is should the static coefficient of friction always be less than the kinetic and the kinetic always be less than rolling?

rolling < kinetic < static
