I find it a bit humorous.. last season late people wanted Jackson to replace Grant full time.. not a year later they want him cut and the next back on the roster to be the lead dog.
Jackson excells in blitz pickups and is a threat out of the backfield.. value until they get a guy with better open field skills to take that role.
Starks is getting a clean release right now, because everyone in the stadium is assuming when he comes in it is a run.. they let him release because he hasn't proven he can fill that role yet.
Personally.. I want Grant has the 15-20 carries a game.. Starks as a breather back.. and a true 3rd down back with elusive open field skills as the third option.. but until that guy hits the roster.. Jackson is the poor mans version.
