And so basically does this mean that a there is more covalent properties in the ionic bond?

Polarizability is the ease at which electrons can be moved away from the nucleus whereas polarizing power is how easily a cation can pull electrons away from an anion. Polarizability increases (it becomes easier to pull electrons away) as the anionic radius increases. Polarizing power increases (increased pull of electrons) as cationic radius decreases.
