combo to same guy in IZ and OZ?

YES!

SOMETIMES blocking calls give you a different combo (but these are rare). For example - on the IZ the Center would combo with the BS/G on the weakside shaded nose away from the call. Vs. the same look - on the OZ he probably would combo with the PS/G, & let the BS/G cut the shade.

This is difficult to explain without X & O! IF there are questions - PHONE me at 804-740-4479 (up till 9:30 PM/EDT).
