If you are worried about losing TD's, you have to look at how a team scores.
Dallas has no receivers who will take it to the house - just posession guys who will get knocked out of bounds, then bring in Jones to score. Also, Jones has shown he can score by himself from long distance.
Raiders have 4 or 5 long range TD threats and a QB who can throw long. Odds are more of those plays end up being TD, while Jordan watches from backfield. Jordan is probably not going to break a 40 yd TD more than once or twice.
p.s. Curtis Martin has only had 2 subpar [1,000 yard] seasons - both while injured, and he was still a solid RB2 those years. Last year was his first full workout in the offseason and it paid off nicely. Can't believe anyone would call out a first ballot hall of famer like that.
