The injury bug bites already

So at my draft in a 7 team league I get pick #6. Now the last few years I have watched Ryan Braun closely and seen the kind of numbers he has been putting up. He doesnt seem to be slowing down and I really wanted to get him this year. Not knowing if he'd be there at #6 I held my breath until it got to me. He was still available, but could I pull the trigger on it? I thought to myself there is a ton of depth at the OF position, so maybe I should grab a 2B (Cano) maybe a 3B (Longoria) because theres not much depth there. So after debating I took Evan Longoria, who I also had last year. Well that backfired big time as I saw him get pulled early in the 2nd game of the season, and now read that hes out for at least 3-4 weeks with an oblique injury. Guess I should have gone with my first instinct. And now im struggling to find some sort of 3B replacement for the short term (and i stress hopefully short term).
