The 23-year-old was Leeds' hero by all accounts as his 101st-minute header at the Riverside earned the Whites a very deserved point.
But former United hitman Davison believes he was largely to blame for Lewis Wing's opener just after the break, when the Boro midfielder was allowed to pick his spot from the edge of the box.
He told LUTV: "This is the disappointing thing for me. The ball is pulled back to the edge of the box but your midfielder is gone missing.
"Kalvin is trying to get back. He [Wing] had far too much time and that's an issue I've seen with Leeds this season. Just tighten it up. Kalvin didn't get back quickly enough. It's a poor goal."
It is harsh, but Davison does perhaps have a point. Phillips, playing defensive midfield, was not in position when Wing opened the scoring for the hosts.
It was his first time playing in his favoured position in nearly two months after Adam Forshaw was injured, and it'll be interesting to see if Marcelo Bielsa keeps him there for tomorrow's visit of Swansea City.
According to The Yorkshire Evening Post, Bielsa might well ignore Phillips's last-minute header at Boro and play Forshaw ahead of him in midfield if he is fit for selection.
