As you might expect, the Twitterverse had a field day with this one, with several of Matthews' critics ripping on him in his first appearance at a major public event since bowing out in round one of the playoffs.
Some others chose to take the time to comment on ESPN not tagging Matthews on his way into the building, which is a bit of a bad miss on the part of ESPN, given that they have recently entered into a broadcasting deal with the NHL. If I didn't know any better, I'd say it's almost as if the cameraman and the producers don't recognize who he is.
In a lot of ways, I sort of understand ESPN putting the focus on Justin Bieber. A simple glance at both he and Matthews' Twitter following will give you an indication as to who will draw more attention. Matthews and his 223K followers may be a star, but he does not measure up to Bieber and his 113M followers. Bieber is a global mega star.
Still, you have to wonder what the ESPN producers were thinking, missing an opportunity like that to shine a spotlight on the National Hockey League and one of its brightest stars.
