ASK THE EXPERTS appears weekly from training camp through the Super Bowl with answers to a new question being posted Thursday morning. How the guest experts responded when we asked them: It's the season of Festivus and the annual airing of grievances. Who has disappointed you most this season?

JUSTIN ELEFF

I am trying hard not to pick on Julio Jones here for a particularly ill-timed injury. His absence pretty much sealed my fate in PPR, but guys do get hurt -- and at least he lasted a lot longer than Keenan Allen, my second pick on the same team. Instead I'll pick on myself, for being very wrong about Blake Bortles in 2016. I didn't actually wind up drafting him anywhere, thankfully, but if you go back to the Experts Poll in our magazine you'll see I was very bullish on Bortles and Allen Robinson, and both proved to be pretty useless week to week. I still hold out some hope that the next coaching staff will turn things around; it should definitely be possible to get Robinson kickstarted, with or without Bortles. Or maybe I'm just fated to have the same answer to this question in 2017.

So many choices…. Have to go with probably Blake Bortles and only because he killed off so many other players after a promising 2015 season. Allen Robinson really is a talent but was a dog this year. Allen Hurns was a huge value in 2015 and a complete waste. We knew the rushing effort would be bad with the Jaguars but Bortles' inability to pass killed an offensive coordinator, then a head coach and overall he was central to the team-wide collapse.

IAN ALLAN

I’ve been disappointed in Donte Moncrief. I was expecting big things from him. He’s a receiver I had high on my board entering the season, so he was a key player for me. He missed five games with a broken shoulder, and that’s fine — I understand that injuries are part of the game. And I will give him partial credit for scoring touchdowns in all six of his injury-free games. But he’s also averaged only 45 yards in those games. I expected a lot more. They’ve got Andrew Luck at quarterback, and he’s throwing the ball all over the place (averaging 279 yards per game), yet Moncrief has been plunking along as just a lesser, supporting piece.

DeAndre Hopkins and Jamaal Charles. Hopkins has been mediocre at best. Chalk some of that up to his quarterback. Charles was the big tease of 2016 and if you took a chance on him in the draft you were rewarded with a whole bunch of nothing. Either or heaven forbid both of them on your team was a recipe for disaster this year. They were huge disappointments although some of the blame should come back to me for believing in these "miracles."

ANDY RICHARDSON

Very hard to think of anyone as disappointing as Allen Robinson. He had a couple of eye-opening grabs in the preseason that made me confident he'd have a big year. I drafted him late in the first round in a couple of leagues; painful to think of the players I passed up for him. If we want to talk mid-round picks, other Jaguars come to mind: Allen Hurns, Blake Bortles. So maybe a lot of it is Bortles' fault. Other wide receivers come to mind: Randall Cobb, Jeremy Maclin. These guys killed lineups for weeks before it was finally clear they had to be benched.
