WWE has tried time and time again to get guys over by having them squash jobbers in their first couple months.
This is not something new. The true test will be what happens say a month from now. Do they have the guts to let him mow through the WWE roster, or will he turn into another WWE superstar, tradining wins in every rivalry they put him in.
And honestly...there will never be another Goldberg. Never will there be someone with that size, power, agility, in-ring psychology, technical ability, etc. who just happens to get a monster push.
