Heres the story i heard..
The Giants signed dorsey levens and told him that he was to be used primarily in the redzone. I head Fassel was the one that told Dorsey this. Also the Giants tried to sign Stacey Mack earlier this year which is more proof that they dont want Tiki getting tired out or injured in the red zone.
But I'm not sure they'll actually give Leven all those carries. I mean, he did average 5.5 yds/carry last year, but only one TD (running... one receiving as well). I think in crunch time, Tiki will HAVE to get the goal line carries.
