Should I take Barber or Jackson?

Well I hate to be the first person to say this , but take Barber. Not that Jackson is a bad choice, but look how Larry Johnson fared last year after holding out, took him 4 weeks to get more than 60 yds rushing. I just feel that with that high of a pick you don't want to hope for a guy to be in game shape, you want one that's ready to fly out of the gates right now.
