No, I would not make the deal. Tulowitzki has really struggled thus far. Additionally, if pitching is the weak spot of your team there is no way you should consider trading Oswalt. Yes, he's struggled a little bit, but so have many pitchers in the early going. The reasons for this could range from the effects of the cold weather to pitcher's not being in their routine yet. Even if Tulowitzki was performing at the same level he did last year (and certainly his struggles could be due to the cold weather, early season slump as well), that still wouldn't justify giving up Oswalt in my mind especially considering the relatively marginal gain from Hardy to Tulowitzki.
