Weak tackles = tackles that result in fast play the balls. Go find a stat on that so you can effectively engage in discussion on it.
My critism of him in this area is he tends to get caught under a player too often but I'd prefer that than miss the tackle altogether. The player up top is responsible for the wrestle and we are not winning it at all and I've been saying that all year. What I don't understand is if there is 3 in a tackle why it is always Rein making a week tackle? Surely they all are?
