If you exclude penalties Walker actually has more Championship goals than Godden.
All rather misleading though, fairest way is NPG/90 (non penalty goals per 90mins) this way you're factoring in minutes played & the fact one is a regular penalty taker.
Championship overall:
Walker 0.19 NPG/90
Godden 0.37 NPG/90
For City (Championship only) their stats are a lot more even than you might expect given Godden's excellent ratio this season:
Walker 0.36 NPG/90
Godden 0.38 NPG/99
Overall Careers to date - All EFL & Cup competitions (excludes non league)
Walker 0.42 NPG/90
Godden 0.39 NPG/90
Both very good strikers with good scoring rates.
I still think Walker will come good. As others have alluded to, at Walker's age Godden had just joined League 2 from non league. They have had very different career paths with Godden definitely improving with age.
Walker needs to find a club, system & style that suits him & nurtures him to really deliver on his undoubted ability. Will that be us? Remains to be seen but certainly looking less likely. I wouldn't bet against him smashing it elsewhere though & lots of hindsight posts about how we should have kept him à la JCH or similar.
