I, as a Cards fan, think Adams was wrong in giving a little glove to the dude but it wasn't anything malicious and the fan gave Adams it right back with showing him the glove and some smack. I think it's just good natured banter/ribbing on both sides. However, his shove could have caused greater issues because it was determined that the person who made the catch, had recently recovered from knee surgery and that shove could have aggravated something.
I think the league should fine Adams and remind players that there is no laying of hands.
Well put.
