I hate to introduce facts into this melee, but statistically Parker is still the better goalline back over their tenure with the Steelers. Davenport has 3 rushing TDs inside the 5 in his two years in Pittsburgh, Parker has 10. Parker also has more attempts this season so far 5 carries to Davs 3, obviously he hasnt converted them, which is indeed a bad sign.
Davenport has never been a very good short yardage back (statistically this is a fact). I would say he is having a lot of success this season so far because when Parker is in they run, and when Davenport is in they generally pass, but occasionally run. Davenport is seeing a lot more space when they spread the field for him. Until Parker gets more involved in the passing game this isnt likely to change. But on the other hand Davenport has been stuffed on some important short yardage plays as well- the question is, when it gets down to crunch time in key situations of division type games, will they really trust Davenport to come up with the big play?
Its argueable- and if Dav continues to have success it will definately make a stronger case for him. But if there is a question mark I have to think they will go to Parker in the critical situations. If you're a Parker owner you should be hoping for some losses and a tough fight for playoff seeding.
