I never insinuated that the Bears weren't aware of the cap hit. I said that if I was a fan, I would like not love the move, in part because the WR they acquired has to be paid (i.e., is not on a rookie contract / is not a draft pick). I don't think the Bears management is good, but they're not incompetent. I even agree with your second point. It doesn't stop them from making more moves, it's just something to be considered.
It's OK to just disagree with a post or feel you could have made a point better without being a jerk about it.
