This work provides original insights to the better understanding of the complex structure–activity relationship of ZrIV–pyridylamido‐based olefin polymerizationcatalysts and highlights the importance of the metal‐precursor choice (Zr(NMe2)4 vs. Zr(Bn)4) to prepare precatalysts of unambiguous identity. A temperature‐controlled and reversible σ‐bond metathesis/protonolysis reaction is found to take
