I would say that is wrong. Watched a few games with Kerr playing. Like I wrote earlier in the thread. He's more of a rich mans Tomas Holmström. Is he a play driver? I don't know because that term can be very broad and very narrow.
He definitely created chances by himself, was an immovable object on the ice, owned the slot and corners, created space for teammates and could fight with the best of them.
I'd say his biggest negative was the constant injuries especially his early knee injuries which hampered his skating. He became more of a PP-specialist after the leg and knee injuries and his effectiveness at ES obviously suffered a bit.
Nowadays I don't think the term is too broad or narrow. Since there's more than enough shot data to use, a play driver can now be described fairly specifically as a player who appears to have a tendency to result in more shots/scoring chances go in favour of their team when they're on the ice at 5v5, and/or fewer shots/scoring chances against. This doesn't explain how or why these trends emerge, just that they do.
These models take a wide range of data to come to these conclusions, including WOWY data. This means, for example, that when you have your Lebda playing up with your Lidstrom, the numbers would (likely) show that the Lidstrom continues to perform strongly in the extra minutes he plays without Lebda and assigns him more credit for the strong results that he attains while on the ice with Lebda (and less credit to Lebda)
In the case of a player like Kerr, considering the number of goals and points he scored, I am sure he created many of his own chances, and I'm also sure his linemates created many chances for him. It would be impossible to describe what a Tim Kerr 5v5 shift looks like in one sentence as there would be a wide variety of outcomes over dozens of shifts per game and hundreds of games in a career. But I think it's likely that he's the kind of player who, due to his limitations, didn't necessarily cause or see more chances take place while he was on the ice, but due to his obvious strengths, saw a more concerted effort take place to funnel chances through him. I think knowing his limitations it's very likely that his teams saw more chances go against the team with him on the ice as well.
And I guess I should explain the whole reason I brought this up to begin with. I don't think, after years of watching Cam Neely play, that he was like this. I think he was more a part of the flow of a game in all three zones (certainly more in the offensive zone) and less of a turret tower - his offense was generated in the "right" way as opposed to catered to him (which Kerr's may have been to a degree, though like I said it's obviously not possible to describe a typical Kerr shift or goal with any accuracy). Neely's play was more translatable to all game situations while Kerr was successful in very specific ways. In retrospect, the players he played with seemed to do alright creating those conditions, but it may have come at a cost.
