I thought both guys were really civil and make it a point of emphasis not to simply come out and bury the coach, even if that's exactly what their comments and criticisms did. They did it with great tact, never directly saying "coaching has let them down" even when they repeatedly mentioned needing more "creativity", which is, in fact directly connected to coaching. Coaches can and need to be creative, players don't have that luxury. When a coach does it, it's a good thing, when the players do it, it's "freelancing", and frowned upon.
So every time they mention "creativity", it's a direct shot at the lack of creativity from the coaching staff.
But as Simms said, this team is "stacked", and there's "no excuse" why they shouldn't be a contender this year. If they fall short, it will be the direct result of subpar coaching.
