Excellent point Justin. He has nothing left to prove-or does he?
Should he continue in the long cars where the numbers are fewer and go on to attempt to prove that his driving and team could have something to do with his success beyond Alan Johnson's tuning? It's only my opinion but I believe that for many, his championships will always be considered a direct result of Alan if he doesn't continue to be competitive once Alan has departed. He could even be fortunate enough to make his name in spite of Alan's departure and if everything works as planned, he could surpass Alan's new long car thereby proving a great deal for the Schumacher name.
Lastly, I would have to say that the competition in Funny Cars is greater than that in the dragsters but, again, that's opinion.
