I know y'all wanted it to be Meek, Jay, Cole or Kendrick but those are all high value targets just like Drake. With a high value target you don't even need to find dirt, just dust. Too much for them to lose.
But Pusha occupies just the right space to put Drake in a bind. He's not relevant enough for dirt to be easy to dig up nor interesting enough to sway momentum. He's known JUST enough that Drake might feel insecure if he ignored the Infared diss, not popular enough to get any mass support, yet someone who could still give Drake credibility if knocked off. An easy target that looked like it would only hurt him if he ignored it.
I don't think anyone else was really in the right spot to pull this off. Just an amazing combination of factors. This is why Jay was so selective with his beefs. In hindsight going at Camron was really dangerous.
This is the first true humbling Drake has gotten. It's going to be interesting to see how he handles it.
