We are thin at QB right now, but I have faith in Day & Yurcich & Wilson to get the best out of the talent we have (and whoever we bring in) as we wait for Jack Miller and then the 2021 QBs to get here.  While NOT IDEAL... I think we'll be alright. 

OkSU started Taylor Cornelius (Preferred Walk-On) last year and he did pretty well. https://newsok.com/article/5605999/oklahoma-state-quarterback-taylor-cornelius-is-ready-for-a-second-chance-at-his-first-college-start

Of course, Baker Mayfield was also a PWO: https://www.sbnation.com/college-football/2017/12/9/16756056/baker-mayfield-walk-on-heisman

QB evaluation and talent development is an art. I think that Day & Yurcich & Wilson have the pedigree in QB scouting and development.
