if I change 

Team<FootballPlayer> adelaideCrows = new Team<>("Adelaide Crows");

to

Team<FootballPlayer> adelaideCrows = new Team("Adelaide Crows");

Would it be wrong or will I get any error later? And why ? wildcard cannot use at class level? like

public class B <? extends A>

    You're instantiating a raw type there. The compiler will let you do this, for compatibility with legacy code, but you shouldn't. If a constructor or method calls for type parameters, you should provide them (or allow the compiler to infer them using the diamond operator, per the first example). – jsheeran Jul 18 '17 at 07:54
