You're right, we've devoted much more than what the Chiefs did in the draft for Jones. Much much more.
The issue is we've not played good defense for most of McDermott's tenure. At maximum he's ranked high at times - however situationally, strategically, schematically and his timely defense has been atrocious.
He's a fine leader and he's brought a new respect to our organization. That's all fine, but he's not a hugely talented game day and game prep coach.
Wait, you want to blame the talent evaluation, but you want to give a first and more for Olave, when he can be had for far less?
