I think Enstrom gets flack for being small and people see any instance of him getting beat in any way as proof that he's too small to be effective. It sticks out more, is more memorable and thus he gets a bad rap undeservedly.
Little doesn't have a bad rap, he just doesn't get any praise despite his consistent offensive production. I think the reason for that is that Little isn't as noticeable on the ice as other players and you really only hear his name in the seconds before the puck ends up in the other team's net. For a first line forward, I think people expect to see more fireworks throughout the game and it might give the uninformed watchers the opinion that he's simply riding Ladd and Wheeler's coattails. The announcers hype big hits and good scoring chances nearly as much as goals, and Little has very few of the first and not that many of the second (because the puck goes in the net almost every time he shoots it, best shooting percentage on the team). He gets no credit for good possession play matched against the other top lines nor for his ability to draw penalties while rarely ending up in the box himself. There is very little bravado to his game but he's quietly consistent in boosting the team's possession and scoring. At the end of the day, he's almost a polar opposite to Kane. When Kane was on the ice, you couldn't help but notice. Kane was one of the players on the team with the consistently worst shooting percentage though. In his defense, he did also help his team possession wise.
Kane video of him shooting the water bottles off the net one by one. Ahh...the magic of video editing and at least a few thousand retakes.
