We're roughly halfway through the fantasy football season, so rather than bring a standard 5 Facts to Know article (especially considering FantasyFootballCalculator.com. Surprising indeed!

Biggest Flops: Jimmy Graham, Vernon Davis
Jimmy Graham was supposed to take the league by storm once again, hooking up for multiple touchdowns with his Pro Bowl quarterback. But due to low targets in a couple games and mostly sitting out against the Lions, Graham has only turned in two startable performances in six games, good for the eighth-best tight end in fantasy football - not good for a first-round fantasy selection.

Over his nine-year career, Vernon Davis has always been more touchdown-dependent than most tight ends. This year it's more the same, but he's simply not producing. He only has 142 yards and a pair of touchdowns in one of the more run-heavy offensive schemes. Outside of his Week 1 performance against Dallas, he has been very quiet in the passing game translating to being unusable in fantasy football for the time being.

Most Startable Weeks: Greg Olsen, Rob Gronkowski
Both players are tied for six startable weeks, and neither player has had to deal with their bye week yet. In fact, with Olsen putting up six top-12 weekly performances, he's the second-best tight end in the league right now. Olsen is performing a lot higher than his average draft position after being taken as the sixth tight end off draft boards.

Gronkowski is performing well too, as many were concerned for his health going into the 2014 season. Many drafted Gronk in the second or third rounds, and have been rewarded six startable fantasy weeks and the fifth-best tight end in fantasy football.
