Not sure if we were ever set at OL. Chiefs have been playing without a real OC for 2 seasons, nothing at LG and a rapidly declining RG for about 3 years. We simply spent a late 3rd for Niang and a 7th for Allegretti to address those issues (including lack of a swing tackle).
I always thought Dorsey did a very good job of finding linemen. I don't like his resignings like Fisher with 2 more years under control, and LDT but looking back he did care about Smith's safety.
LT - 1st overall for Fisher
OG - Traded for a known commodity in Grubbs, drafted Fulton, LDT, Ehinger
OC - 2nd for Morse
RT - Signed the best in the NFL in FA at a young age
I think we need a similar approach for the OL and more importantly have continuous upgrades which is the primary issue right now as we have neglected the line for a few years now and need a bunch of bodies there.
