I would bet New England Patriots tight end Rob Gronkowski is a blast at parties. I mean, I've heard stories and it doesn't seem like much of a stretch that this gregarious, attention-seeking fellow who once appeared on a reality dating show would be lots of fun to hang out with. The problem, for our reasonable purposes, is he's just not as much fun to own in a fantasy league anymore. It's true that Gronkowski could be as talented a pure receiving tight end as the league has ever seen, but here's a fun fact: We like our players -- fun or not -- to actually appear in football games. Like, perhaps give us 14-plus games per season. Sorry, but that sure doesn't seem like Gronkowski anymore.
