Jerry Sandusky's Lawyer -- My Client Is SCREWED

You know you're up the river without a paddle when your own lawyer has no faith in you -- which is exactly the case for former assistant Penn State football coach and accused child rapist Jerry Sandusky.

Jerry's lawyer Joe Amendola just told reporters he'd be "shocked" if the jury acquitted him on all charges -- adding he'll "probably die of a heart attack" if his client beats the rap.

Jerry stands accused of 48 counts of criminal child abuse -- after allegedly abusing 10 boys over a 15-year period while working as the assistant football coach for Penn State.

Jerry's lawyer likened the trial to climbing Mt. Everest -- calling it a "daunting, daunting case."
