I'd take it...I've always valued starters more than RPs, and he can potentially boost more of your categories, plus Rodriguez could lose the job if he's on a short leash and doesn't pitch well (Brad Lidge/Tyler Clippard are both solid options that they could use if things don't go well).
I'd lean towards taking it. Adding qs makes this a starter-friendly league. Wandy isn't anything tremendous, but he's not bad. The BBM rankings for last year put him as the 54th-best pitcher. He hurts you in whip, but otherwise he's solid.
It is a risk, though -- if Storen has a setback, which is always possible w/ pitcher injuries.
Btw, are there any weekly limits in your league? Transaction limits, # of starts limits? Just worth considering in terms of streaming.
No, Henry won't have the job for long. Dude is strictly a vulture saves guy. I'd keep him for those saves and then start streaming favorable SPs off the wire. I want those saves plus streaming SPs way more than Wandy's mediocre season stats.
