My guess is:
1) AJ will win immediately with the new team
2) Schumacher will become just another team that wins once or twice a year
The truth is the teams pretty much have all the same equipment. Top fuel is all about figuring out how to get the power to the pavement without spinning the tires or breaking the engine. AJ clearly knows how to do that that as he has won championships in TF with three different drivers (his brother, Gary Scelzi, and Tony Schumacher). The Schumachers were just another team before AJ, they'll be just another team without him. Further proof? How are Schumacher's three funny car teams doing? Not too good. Scelzi won a title in FC three years ago, then his crew chief left and he's now down around 14th in the points. You can't just plug anyone in to the crew chief position and keep winning. The nitro classes are more about the crew chief than they are about the driver.
