Jackson's workload with Atlanta

It became evident during the latter stretches of 2012 that the Atlanta Falcons needed to move on from Michael Turner as their primary rusher heading into 2013, and so it was with little shock that his release was met earlier this offseason (Turner has yet to land with another club). To replace him (and hopefully provide more oomph on the ground), the Falcons signed Steven Jackson, formerly the lead back for the St. Louis Rams. Should we expect a workload similar to what Turner used to provide Atlanta (well over 300 carries per year)?
