Narrative:

I was cleared to descend via CHSLY3 landing south. We had a hard altitude programmed at bluej at FL270. We set 6000 feet into MCP. The aircraft was on the VNAV path. The descent began and grew steep and I could not maintain the path and the reduce speed. ATC asked if we would make our restriction; we thought we could then asked for relief at nodew. ATC issued a new clearance and asked us to call them about a possible altitude deviation. We landed without incident. I called the ATC facility and talked with the controller. He emphasized that this was a recurring problem with the 737-800 fleet on this arrival when landing south. The controller also stated there would be no deviation filed. I feel if this is a recurring problem perhaps a point of emphasis could be placed in the company pages under optimum profile descent arrivals section. It appears the opd is very steep in the 737. A point of emphasis could be placed in the company pages cautioning the 737 fleet of this occurrence.

Title: B737 flight crew reported that the CHSLY3 ODP plans the descent path so steep that the speed constraints are not achievable with the use of the speed brake.
