You are quite correct!
The 757 was designed by Boeing as a direct replacement for the 727, however the original 757-100 found no interest with the airlines at all and as such only the -200 went into production until much more recently when the -300 was made.
American like most US carriers had loads of older 727s and chose the 757 as a same size replacement and also the 767 for services requiring growth. The two having been made with a common type rating.
However in recent times the 737-800 makes an even better 722 replacement, flying near enough the same distance but using only half the fuel of the old 727.

As much as the 757 was designed to be a 727 replacement, her introduction really came at a time when the 727 was just into its prime as the short- and medium-haul "weapon of choice" for the US majors, and many others around the world.
I think the 757 ended up replacing the 707 even more so, as at time, aircraft such as the DC-10, L-1011, and to a lesser extent, the Airbus A300/310 were flying routes that the 707 filled well, but the widebodies were operating with a bit too much capacity. In addition, some 707 flights were downgraded to 727 and 737 equipment, clearly too small for some jobs. The 757 fit the bill perfectly, and thus the two types were able to coexist quite well for some time, until the 727 was ready for replacement.
I can remember, in my early days with my company, Eastern, Republic, and Delta were just introducing 757 service, it was hailed as the aircraft of the future, and was referred to as the "perfect 707 replacement" by a pilot I sat next to on an ATL-MIA 757 flight in the mid-80s. Those were the end of the golden days, especially when you could go to almost any major airport and see at least a few 707s rolling around!

I will agree with CODC10 on this one. While Boeing designed the 757 to be a direct 727 replacement, albeit one with higher capacity and greater range yet needing less runway to land and so on it eventually created for itself a separate market niche. With the growth in US air travel in the 1980s the 757 was well-suited for transcon flights and mid-range heavy routes. They were thus bought in huge numbers and deployed as such, leaving the 727s on shorter sectors and those short hops with very high frequencies in particular (BOS-LGA-DCA for example). Hence the coexistence of the 2 types for many years. The real 727 replacements now are the 737-800 (perhaps that is the definitive 727 replacement) and the A320 (which filled the need in Europe).
