Every team has one. That one player that fans just look at and ask, "Why is he on this team?" From players who repeatedly get injured to players who are just not that good; no matter how hard they try, they can't contribute to their team.
If you're a useless player in a place like Columbus, you don't have much of a problem, but if you're in a place like Toronto, you are pointed out and vilified to the greatest extent.
Keep in mind that some of these players aren't exactly useless, they're just the least useful on their team.
