You're justifying the belief that a WR is more important the a LT.
While that's certainly not the rule of thumb, in the comparison between these two players and their impact on both teams, the loss of Harvin is greater than Baluga
Harvin was supposed to help improve a WR corps that was pretty average with Sidney Rice, Golden Tate & Zach Miller. Now they have no dynamic playmaker who can play outside, in the slot or in the backfield. It's a huge loss & the biggest injury loss of the preseason
Baluga's an important loss and a big injury loss, but that GB o-line was pretty awful last yr as I previously mentioned. Dan Koppen being done for the year is a bigger OL loss than Baluga if we're gonna keep it real.
