2man baseline postion

[cloverdale]

had a problem tonight...im baseline watching a low post player who is a large/wide body...ive got a great angle and look at everything but ball comes in to him at low post makes a great move toward the basket and I lose the defender because this body is WIDE cannot see any contact and if there was any he doesn"t move...he complains that he is getting hit and I do believe he is but I cannot see it...I know enough that the trail has to pick up on anything from behind but i'm looking for any body contact and any strafing of the arms...question is how do you position yourself for this type of situation? I thought if the play allowed me to take a step across the baseline facing the rim would that be considered ok if it gave me a better look at the defender?
