What's gone wrong with Emeka Egbuka?

Since Tampa Bay's Week 9 bye, Egbuka is averaging almost 10 targets per game but only 4 catches per game.

Weeks 1-5:
- 87.9 fantasy points
- 17.6 fantasy PPG

Weeks 6-14:
- 56.6 fantasy points
- 6.3 fantasy PPG

He has topped 60 yards ONCE since Week 5. He's gone from one of the most efficient to one of the least efficient players in the space of a few months. It's not as if the Bucs are at full strength on offense either. No Mike Evans, near-invisible Chris Godwin, heck even Bucky Irving has missed big chunks of this period.

So ... what's stopped Egbuka from taking over? Is it a Baker problem? Is it something he's doing wrong and can improve on? Coaching/play-calling issues? I'm sure there are probably more than a few fantasy managers who are wondering what to do with him/how to view him ahead of the playoffs.
