The Jags staff writer answered my question
Nathan from York, England:
How does Corey Grant look in camp? He's got serious speed but do you think that will transfer into impact on the field now and in the future?
John: Grant has shown serious speed in practice – and he showed it in the scrimmage Saturday. I think we’ll start seeing how it translates on kickoff returns in the preseason. He’ll either shine brightly then or not, and that will probably dictate whether or not he’s on the roster. My guess is he’ll shine and that he will be around. We’ll see.
I watched the scrimmage. He returned a kickoff to the end zone but was deemed tackled further back. He really is quick. It's him or Bernard Pierce I think and as good as Bernard has looked Corey offers you a higher ceiling and a different skill set.
It also might be time to start registering fantasy interest. What do you want to play? I'd be happy to admin a league or two if DT isn't here any more to retake that mantle. I'd be up for playing standard, auction and IDP. I liked using NFL.com as the host site too but do share your opinions.
