I'm surprised that no-one has brought this up, but Ian Bell would have been wearing a helmet when he top edged the ball into his chin. The helmet grille clearly hasn't stopped the ball, in fact, the ball seems to have completely missed it. This raises a couple of questions for me, but I wonder what others think.
The first is that I don't believe the grille position extends around under the chin enough. Certainly, my Ayrtek fits me better than either a Masuri or an Albion, and I do worry that an edge or sharp lifter would get to me due to the position relative to my chin. As our resident expert Tom, what's your view on this?
The second is whether, had he been wearing his Ayrtek, he would have suffered less damage...?
