Coughlin was referring to his decision to attempt the field goal - which would have been the longest in Tynes' career - on third-and-19 with 15 seconds left instead of running another play to get closer.
The Giants had no timeouts but could have run a play to the sidelines to stop the clock.
"We had the game in our possession, we were in field-goal range and we didn't get it done," Coughlin said. "All of those things, put the blame right here, it is right where it should be. The game was in hand, we let it get out of hand. All the analysis afterward is fine and dandy, that is what we all do for a living, me included. Analyze, analyze, analyze."
The bottom line is that the Giants are 0-2 in the NFC East and 2-2 overall.
Yet, the Giants don't seem as if they're panicking. This is, after all, a team that started the 2007 season 0-2 and went on the win the Super Bowl.
"Hey, we're 2-2 right now," quarterback Eli Manning said "It's not the ideal situation, but you could be a lot worse. Philadelphia is 3-1, we're not far out. There's a lot of football to be played. We've still got four more divisional games. It's a lot of football left and we've got to worry about Cleveland and get back to winning and there's no point in getting down now. Everybody knows we're going to see Philadelphia again the last game of the regular season.
"I have a feeling that's going to be a big game for us."
If there is a concern, it's injuries.
Giants safety Kenny Phillips sprained the MCL in his right knee against the Eagles and will likely miss Sunday's game against the Browns.
Coughlin also did not have encouraging news regarding wide receiver Hakeem Nicks, who sat out the loss to the Eagles with swelling in his knee and pain in his surgically repaired foot.
Nicks has not played since a Week 2 win over Tampa Bay.
Coughlin said he isn't sure Nicks will play against Cleveland.
The New York Jets agreed to terms with cornerback Aaron Berry, who was arrested twice this summer and then cut by the Detroit Lions.
The Jets made the deal because All-Pro cornerback Darrelle Revis likely is out for the season with a torn ligament in his left knee.
The Lions terminated Berry's contract in July after his second arrest of the summer in Pennsylvania. Berry, who is from Harrisburg, was arrested in July on three counts of assault. Less than 4 weeks earlier he had been arrested on suspicion of DUI, failure to stop and render aid from an accident and other counts.
In other news, wide receiver Santonio Holmes is expected to be sidelined at least a few weeks after injuring his left foot during the Jets' 34-0 loss to the San Francisco 49ers.
* Tennessee's Jake Locker has no structural damage to his left, non-throwing shoulder and coach Mike Munchak said the quarterback is day-to-day.
Locker dislocated his shoulder Sunday early in a loss to Houston when sacked by Texans cornerback Glover Quinn.
Munchak says the Titans will know in the next couple days whether Locker will play Sunday at Minnesota.
* Denver placed center J.D. Walton on injured reserve with a broken and dislocated left ankle he suffered in the Broncos' win over Oakland on Sunday.
In other news, Broncos linebacker Joe Mays said he's not going to change his style after getting suspended a game for a hit that sent Houston quarterback Matt Schaub's helmet and a piece of his ear flying. Mays was also fined $50,000 but got to keep his $200,000-plus game check.
He immediately apologized to Schaub for the hit during the Texans' win at Denver on Sept. 23, which Mays called unintentional. Schaub accepted his apology.
* Kansas City coach Romeo Crennel reiterated his stance that Matt Cassel will be the starting quarterback when the Chiefs host Baltimore Sunday.
Cassel has thrown seven picks and lost three fumbles through four games this season, and many fans are starting to call for backup Brady Quinn, who hasn't started a game since 2009 with Cleveland.
