Like the other posters I'm pleased he's doing well for England, still scope for improvement physically, mentally etc, he needs regular cricket in 2016 not being injured so much & his back to hold up, like his action, decent run up, good temperament & bowls good yorkers & slower deliveries.
Batting wise he is poor, Don could teach him a bit (he was no mug himself), runs lower down are always useful, Tom Craddock wasn't much of a bat when he joined but he contributed a few useful innings & more importantly developed a decent defensive technique making himself hard to get out, Reece could aspire to that at least.
