JACKSONVILLE – Gus Bradley set the tone quickly.

"There are self-inflicted words that are hurting us – badly," Bradley said Monday afternoon.

With that statement, the Jaguars' third-year head coach established the theme early during his next-day press conference a day after a 16-13 overtime loss to the Indianapolis Colts.

The Jaguars had chances to win at Lucas Oil Stadium in Indianapolis, Indiana, and Bradley talked about those. He talked, too, about a ton of positives. But mostly, Bradley talked about missed opportunities and mistakes, doing so in a more severe tone than he usually takes when speaking to the media.

Bradley stressed late in the press conference he wasn't trying to be negative.

"Games like these, they really challenge your conviction in how you want to approach it," Bradley said. "It might be where everybody wants us to become negative, but I know that becoming negative isn't going to work. It's not.

"Challenging our guys and demanding we do things right, and are disciplined and focused – that's what we need. We're going to do that and we need to that. I felt like we were doing that, but it's not showing up. In this game, it bit us a little bit."

At the same time, he absolutely had the demeanor and tone of a coach who knows something has to change – and improve. He used the phrase "self-inflicted wounds" often, particularly when referring to 13 penalties for 92 yards.

Five of those penalties were for 42 yards on the Colts' lone touchdown drive.

"These penalties … good teams, consistently, don't have even a series like that," Bradley said. "Far too many penalties in that situation."

Bradley also discussed the status of kicker Jason Myers, who missed a 53-yard field goal with :01 remaining in regulation and a 48-yarder with 8:13 remaining in overtime. Each kick would have won the game.

Bradley supported Myers Monday and said the Jaguars have no plans to try out or sign a kicker to replace the rookie.

"When we first signed Jason and we made that decision, we knew there were going to be some waves," Bradley said. "I like his mentality. We're very confident in him."

The self-inflicted wounds weren't just about defensive penalties. Right tackle Jermey Parnell had a holding penalty on the first drive of the third quarter that negated a 15-yard run by rookie T.J. Yeldon and took the Jaguars out of field-goal range.

That was one of six drives in the second half or overtime on which the Jaguars reached Colts territory. Having scored 13 points in a productive offensive first half, the Jaguars did not score on any of their eight possessions in the second half and overtime.

"That's what's disappointing, and it's self-inflicted wounds again," Bradley said. "A botched snap, not handling it right, penalties … those types of things we have to clean up. It comes down to being disciplined and staying focused throughout. Those are some of the issues that we're dealing with right now.

"I think the guys recognize it, but in order for us to go where we want to go, we have to clean those issues up from our game."

The Jaguars produced 421 total yards Sunday, with quarterback Blake Bortles throwing for 298 yards, wide receiver Allen Hurns registering 116 yards receiving and running back T.J. Yeldon rushing for 105 yards.

"When you see production in moving the ball, but the finish isn't there, and (when you see) these self-inflicted wounds … that's frustrating," Bradley said. "It's very frustrating for the coaches and players. We've got to get over that hump. I think there's a general sense we're making progress with the team. I think they feel like we're making strides, but we're not there yet, obviously."

Bradley was asked if he was angrier after Sunday than previous losses.

"Disappointing," he replied, "because we did miss it."

Referring to the missed opportunities and mistakes, Bradley said, "I'm probably a little confused, just like our fan base is. When you see good plays, when you see big plays, when you see guys who are taking shots and guys making plays and it feels like it should and you don't see the consistency and the ability to stay the whole drive … have a 13-play drive where you finish it with a touchdown …

"Where's that part of the game? I think that's what's disappointing right now. We've got to do it."
