Amid the chaotic scenes at the end of Wednesday's match between FC Dallas and the San Jose Earthquakes -- a game in which FCD defender Jair Benitez missed a stoppage-time penalty that allowed San Jose to escape with a 2-1 win -- the present form and mental state of Dallas attacker Brek Shea still managed to take center stage.Dallas is currently tied for the fewest points in the league alongside Toronto FC and the Portland Timbers and Shea's performances have mirrored those struggles for much of the season. Fatigue caused by his frequent stints with various U.S. national teams over the past 12 months has been the usual explanation, but there have been other incidents that have indicated all is not well with the 22-year-old. Shea suffered a three-game suspension for kicking the ball at an assistant referee in a match against Columbus back on May 12. He has tallied just three times in 2012 league play and was also part of the U.S. U-23 team that failed to qualify for the Olympics.On this night, with usual forward Blas Perez not only injured but back in Panama due to the death of his father, Shea was deployed as a lone striker in the first half. While Dallas threatened often from set pieces, he labored to connect with any of his teammates and plenty of promising Dallas attacks died at his feet. Things improved (albeit marginally) in the second half when he was moved to his more natural position out on the left wing.So in the 64th minute with Dallas trailing 2-0, manager Schellas Hyndman opted to pull Shea in favor of Carlos Rodriguez; that was where things got interesting. Shea voiced his displeasure at Hyndman as he exited the field and the two appeared to exchange some sharp words. Shea then proceeded to sit by himself on the end of the bench with a towel wrapped over his head as his team's late rally fell agonizingly short.FC Dallas captain Daniel Hernandez was less than pleased at Brek Shea's behavior versus San Jose, saying it showed "immaturity" and that "at this point in the season, we can't have those breakdowns."After the game, Hyndman declined to make Shea available to the media and did his best to bite his tongue as he fielded a steady stream of questions relating to his young star. "I think it's better that I don't make any comments about [shea's] performance," he said. When asked what Shea had said to him, Hyndman responded, "I think it's probably better I don't make that comment, either."Hyndman later said he didn't know what was going on in Shea's head at the moment, even apologizing for not making the player available to the media. Though he then stated, somewhat cryptically, that, "I think [shea's] in enough hot water already." Hyndman said that any decisions about disciplining Shea for his outburst would be handled once the team returned to Dallas.FCD captain Daniel Hernandez was more forthcoming, however. "I thought [shea] was very disrespectful, not only just to Schellas, but I thought to the rest of the team," said Hernandez as he stood near the team's bus. "He's a young guy still, but this shows the immaturity there in him, and I think a lack of professionalism that right now, at this point in the season, the way things have been going for us, we can't have."Nobody likes to come out of a game. I don't like to come out of a game," continued Hernandez. "I'm pissed off when I come out of a game, or when I don't play. But when things are not going well for you, or you're not having a good game, and coach needs to make a change, you have to respect it. At this point in the season, we can't have those breakdowns right now, because we need everybody. We need him. He's one of the stars of our team, and we need him to step up with his leadership and his play. He's obviously one of the best players in the country. In order for us to try to fight to get into the playoffs, we're going to need him and everyone else, 100 percent."The impulse is to think that this is just the kind of bump in the road that most young players encounter, but it has been almost a year since Shea delivered a performance, either for club or country, that had the kind of "wow" factor fans and coaches had grown to expect. Shea's talent level is beyond debate. The big question now is whether Shea has the mental fortitude to fight through this extended rough patch.It's possible that Shea might require a change of scenery if he is to come out positively on the other side. Yet it seems unlikely that MLS would allow one of its young stars to exit the league at a time when his valuation is well below its peak, especially given the current transfer tug-of-war that has taken place over another hot commodity, Houston Dynamo defender Geoff Cameron. A trade within MLS seems unlikely as well given Shea's considerable upside.Some will no doubt suggest that Hyndman is the one who should go. Without question, his reputation has eroded since leading Dallas to the 2010 MLS Cup final and results like Wednesday's don't help, especially with a normal penalty taker like Shea stuck on the bench. That said, FCD's difficult injury glut this season can't be laid at his feet and while tempers appear to be fraying, that's not uncommon for a side that is propping up the rest of the league. Besides, Hyndman was chased by Dallas owner Clark Hunt for years before finally agreeing to leave SMU -- where he had coached for 24 seasons -- to take over FCD. It seems like it will take more than one bad season for Hunt, who played for Hyndman at SMU, to pull the plug.Either way, plenty of eyes -- from Hyndman to U.S. national team head coach Jurgen Klinsmann, and everyone in between -- will be watching to see how Shea fares.
