With two revealing moves in a five-day span, the Jets provided further evidence that Curtis Martin never may play for them again.The trade for Kevan Barlow, which became official yesterday when the former 49ers running back passed the Jets' physical, speaks volumes because they agreed to take on a relatively large contract. Barlow, who has three years remaining on his deal, is due to make $2.5 million this season - not the kind of money that usually goes to a part-time player/insurance policy.
