Southampton boss Adkins upset momentum stopped by match officials
"The first half we were on the front foot and there was a verve about us," the Saints boss said after the 1-1 draw.
"We scored a good goal through Rickie Lambert and could have scored one or two others.
"Unfortunately, the game has changed for us bang on half-time with the goal we have conceded.
"I don't think it was a free-kick from where I was in the dugout, watching the video back, Nathaniel Clyne made contact with the ball first [before Snodgrass].
"The ball has gone in that direction, indicating he made contact first, but the referee has given the decision and we've got to save it.
"That gave them a big uplift and in the second half I thought they were the better team.
"All-in-all, we've got another point. That is eight points in the last four games so we'll take the positives from that and move onto the next game."
