Arian Foster Fantasy Football #1 or not

Arian Foster was everyones first pick in the fantasy football world, but after his latest injury I would think twice about his value. Foster was a good running back at the university of Tennessee, but injury affected his college career production. Last year was a great year for Foster,over 1600 yards rushing and more than 50 catches. It was a brake out year but it's just one year. Don't get me wrong Fosters a explosive back but with his latest hamstring injury, is he worth a number one pick. Foster sustain the injury in training camp, probably the result of a short mini camp following the lockout this off season. After a couple preseason and about twenty carries later the hamstring injury is back. Which would lead me to believe he was never a 100%. Foster played through a injury last year and didn't tell anyone about it not wanting to loss his starting position. A hamstring injury is alot harder to play with than the injury Foster sustain last season,and if not given the injury enough time to fully heal the hamstring could plague him all season long. That tells me it might not be the best year in Foster's career. Second string running back Ben Tate has looked explosive in the preseason. So if you do decide or have already picked him try to grab Ben Tate in the later rounds or free agentcy for insurance.
