No idea what your point is.
All those teams (minus the eagles, which are nothing but an outlier, and would've probably won with Wentz regardless, negating your "point") won with THE QB they wanted and went all in with.
1. Nick Foles had a great offense around him that was built around Wentz and worked great with Foles in it as well (not planned for)
2. Tom Brady - Bucs handed him the keys, he had the entire offense built around him lol, he basically had his pick of talent from day 1
3. Stafford - Rams went all in, and he joined a team full of pro-bowlers
