ST. LOUIS (AP) -- The Rams' offense has a new look just about everywhere.
There's a new quarterback, new running back and a redone offensive line.
But the biggest change might not be on the field at all.
New offensive coordinator Frank Cignetti is responsible for making all of the new - and old - pieces fit together while improving a unit that finished 28th overall in the NFL in 2014.
But don't expect a return to the ''Greatest Show on Turf'' days. Cignetti is keeping previous offensive coordinator Brian Schottenheimer's run-first philosophy.
''Coach Schottenheimer put a tremendous foundation in place here,'' Cignetti said.
