It depends on how much you're valuing ceiling vs. probability of reaching that ceiling, in my opinion.
I think it's definitely arguable that Goodwin's ceiling is higher than Rendon's. If you see Rendon only as a 20 HR guy, you might only project him as a David Freese type 3B (.293/.372/.467 this year) which is definitely valuable but not as big a deal as Goodwin if you think Goodwin is a similarly valuable hitter but as a plus-fielding CF.
I project Rendon as Edgar Martinez and Goodwin as Curtis Granderson with 25 homers instead of 40+ (2008 Tigers type season)
