He did coach Kirksey, Hitchens, Morris, kittle, Fant. Perps forget he was doing Seth LB job before Seth . LW is the reason Eppy selected Iowa- yes, the reason
Woods spent most of his time coaching OLB ... the primary coach of the LBs was Reid. The year before Reid came on board, Woods had full control of the LBs (2012) ... and the LB play that year was not good. Woods took over LB from Wilson, since Wilson shifted over to being the DB coach when Phil took over as DC.
Reid took over full reign of LBs in 2015 ... and that year Woods got moved over to coaching TEs.
There's no doubt that Woods is a mighty fine coach. He got rewarded as such when Kirk gave him the ST coordinator gig.
It's odd that you'd point out that Woods had the LB job before Seth ... he had it for one year ... and didn't do a great job either. In contrast, Seth has controlled the room for 8 years, the LB room has been a strength of the team, the development of players in the room has been impressive, and and he is considered a rising star in the coaching profession.
Looking at resumes ... LeVar started off as an administrative assistant from 2008-11 ... and didn't start coaching until 2012. Wallace has been coaching since 2001. Wallace has experience at Iowa working with all facets of the D (working with DL, DBs, and LBs). He's was mentored by Norm early in his career ... and Norm was a genius at making complex concepts simple for his guys. On top of everything, he has prior coordinator experience when he was at Valdosta State.
I respect the hell out of LeVar ... but from my vantage, Seth has the better resume. Anyhow, I doubt that this was an issue of Wallace getting a promotion OVER LeVar. My impression is that the promotion arose as a function of retention. LeVar may have wanted one too ... however, there likely wasn't the same retention concerns.
Anyhow, Kirk respects the hell out of LeVar ... and has rewarded him accordingly. Does LeVar want more ... or believe he deserves more? Maybe. However, it's not like he's experienced any ill treatment.
