Any driver can go out and buy an expensive and fast car but it does not make you a great driver even if you win a lot over other cars. A great driver can win without the most expensive car.
Same with teams and players. A great team is not one that recruited (or bought in some cases east) the most 5 stars. It is one that doesn't win every play but steps up and makes the plays when necessary. A player that makes that catch when the first down is must have, bats down a pass for 2 points or knocks a ball loose (or just make a stop) to avoid going down in the last minutes. It can be a mental thing as much as physical.
Is this team great, probably not yet, but there are some players stepping up to play great when needed. See where it takes us.
