I would think that "good" wouldn't be good enough. Unless you think that the players we would have picked in the first
and the 2nd round wouldn't have been good too. If I had asked you if the you thought the #16th and #46 picks would probably result in good players I bet you would have said yes to that question too. For myself, Tavon needs to be Great (with a capital G) in order to trump the two "good" the two players we didn't pick.
I will admit that the 3rd round pick we got in the trade (McDonald) is probably going to be a good player, that doesn't change what I perceive to be a flawed strategy. I might take off the capital G and make it him just needing to be great but I would never use the results of any particular trade to justify any strategy. Bottom line is the math is on my side and you know how I love math.
