The aim of this study was to identify the contact situations, within national-league rugby union, that present the defending player with a desirable or detrimental tackle situation. Specifically, the positions of the tackler and the ball carrier were investigated; prop, hooker, second row, flanker, number 8, scrumhalf, fly half, centre, and fullback. A total of 2,759 one-on-one tackles, from 20 rugby union matches, in the SSE National 3 London and South East Division, were analysed. When considering the players involved within the tackle situation, the flankers attempted the most tackles (n = 522, 18.9% of total tackles), and the fullbacks attempted the least (n = 105, 3.8% of total tackles). The centres were the most frequently used ball carriers (n = 377, 13.7% of total tackle situations), and the fly halves were the least frequently used (n = 193, 7.0% of total tackle situations). The most common outcome from a tackle situation was defined neutral, where neither attack nor defence gained ground from the point of contact (n = 1,101, 39.9% of total tackles). The least common outcome was defined dominant, where the tackler won the contest and gained ground past the contact-point in the process of completing the tackle (n = 295, 10.7% of total tackles). When considered as a completion rate, tackles that were dominant, neutral, or negative, were shown 75.1% of the time (n = 2, 072). The position seemingly identified as the best tacklers, by producing the highest percentage of dominant tackles from the amount of tackles that they attempted, was the props (n = 50, 15.2% of their tackles). The scrumhalves produced the highest percentage of missed tackles (n = 62, 36.3% of their tackles), and were deemed the weakest tacklers. Wings seemed the most effective ball carriers, by producing the highest percentage of missed tackles from the amount of tackles they faced (n = 121, 39.0% of their tackle situations). The scrumhalves seemed the least effective, by allowing the highest percentage of dominant tackles from the amount of tackles they were involved in (n = 52, 26.8% of their tackle situations). Using the results of this study, tactical mismatches can be highlighted for teams to exploit within their game plans. Further analysis into positional differences within the tackle is still required, as well as other factors that could affect a tackle’s outcome, and suggestions have been made for future studies.
