This is only a observation, from Past performances. If Jeremy didn't have his heart into racing, the answer is no. When jeremy was leaving Suzuki, he laid down and basically circulated in the outdoor Motocross season. When passed, he didn't fight back for his position. Then when he went to Yamaha, His winning ways came back.
I believe when he went to KTM, in my opinion, it was a step down from the other Factory support he had had in the past. Could he have run upfront, most likely, but win
Now you say after KTM, he did have very good finishes on a 4 stroke 450 ( this is a different animal than a 250 2 stroke)
