  We propose and test a fairly simple idea that could account for the blazar
sequence: all jets are launched with similar energy per baryon, independently
of their power. For instance, flat-spectrum radio quasars (FSRQs), the most
powerful jets, manage to accelerate to high bulk Lorentz factor, as observed in
the radio. As a result, the emission region will have a rather modest
magnetization which will induce a steep particle spectra therein and a rather
steep emission spectra in the gamma-rays; particularly in the
\textit{Fermi}-LAT band. For the weaker jets, namely BL Lacertae objects (BL
Lacs), the opposite holds true; i.e., the jet does not achieve a very high bulk
Lorentz factor, leading to more magnetic energy available for non-thermal
particle acceleration and harder emission spectra. Moreover, this model
requires but a handful of parameters. By means of numerical simulations we have
accomplished to reproduce the spectral energy distributions and light-curves
from fiducial sources following the aforementioned model. With the a complete
evolution of the broadband spectra we were able to study in detail the spectral
features at any particular frequency band at any given stage. Finally numerical
results are compared and contrasted with observations.
