We show that simple monopole fits comply with the old idea of meson dominance. We use Chiral Perturbation theory ($\\chi$PT) to next-to-leading order (NLO) to transform the MIT data to the physical world with $m_\\pi=140~$MeV and find that the spin-0 GFF is effectively saturated with the $f_0(600)$ and the spin-2 with the $f_2(1270)$, with monopole masses $m_\\sigma= 630(60)$~MeV and $m_{f_2}= 1270(40)$~MeV.
