I'm quite confident that was his point. You claim this was a racing incident, while Jakobsen fell victim of Groenewegen's behavior.Please use quotes in context and use the full quote.
The first quote referred to the Jakobsen and Groenewegen crash.
The second quote referred to the Welsford and De Lie crash.
And i think this was nearly as bad as Groenewegen, with the exception that Groenewegen pushed Jakobsen directly into the barriers, while Welsford pushed De Lie into another rider. Other than that, there isn't that much of a difference. The main difference is that De Lie has a concussion, and that Jakobsen went into a coma with a mangled body. They both clearly start to move as they feel they are going to be overtaken. If you imagine the line McClay is riding, to be barriers, and when you look at where Welsford is relative to the dotted line next to him, and where he ends up when he ultimately bodyslams De Lie into McClay, you would understand what i mean. This was 100% on Welsford. Now he starts tweeting about how it is difficult to control a bike at 70kph. He just so happened to be able to sprint straight at first, only when De Lie starts overtaking him, does he find it difficult to control his bike, and he just so happens to start moving towards the rider who is overtaking him. The entire road to his right is completely open, but him having difficulty to control his bike at 70kph, makes him move the other way accidentally. That or maybe it was De Lie's gravitational pull that was too big to resist.
