I don't see this as much of an issue. We're not drawing huge amounts of games - only 5 all season (25%) and 2 of those were in the last 2 games. In fact our scoring record in the 2nd half of games is relatively good, especially the final 15 minutes where we have scored 7 of our 21 goals.
For me the issue is still about scoring in the first half of games. 1 goal in the first 15 minutes of matches (thanks to the corner flag vs Crewe) and 6 in total in the first half in 20 games are very ugly stats. In comparison Luton have scored 23 goals (6 in 0-15mins) in the first half of games, more than we have in total.
Getting the first goal is very important to us - we've only conceded one equaliser all season vs Stevenage and when we get 1 goal, we tend to get more. 7 of our 9 wins have seen us score at least twice which demonstrates how conceding a goal opens teams up. On the other side of that same coin, in the 11 games where we have dropped points (5 draws, 6 defeats) we've only scored 3 goals.
Ironically losing 2 of our better players in Jones and Kelly to injury might just help us score more/earlier as it has forced Robins into a tactical re-think and since that we've already started to see signs of a shift away from the patterns of earlier in the league season but it has consequences too. e.g. The last 2 games have been the only score draws of the season, we conceded the first equaliser of the season vs Stevenage, we conceded only our 2nd goal at home in the first half of a game vs Crawley. Will be interesting to see how the Morecambe game pans out - they concede regularly at home without ever getting hammered but have the worst attack in the league.
