The New England Patriots have almost no margin for error for the rest of the season and Tom Brady has insisted no mistakes can be tolerated if success is to be had.
Bill Belichick's side fell to their fourth loss of the season on the road to the Miami Dolphins on Sunday afternoon, meaning they are now 10-4 and passed up the opportunity to clinch the AFC East title.
Ryan Tannehilll threw a last 14-yard touchdown to running back Marcus Thigpen to give the Dolphins a four point lead and only 1:15 left on the clock.
Brady had led the Pats to victory coming from behind in their previous three matches, but he came up short in this encounter and threw an interception in the end zone with two seconds remaining.
It was the fifth Patriots game in a row that had been decided by four points or fewer and Brady acknowledged that injuries to key players like Rob Gronkowski and Vince Wilfork meant Belichick's side really can't afford to make any mistake from here on in.
"Our margin of error is very slim," he told Boston sports radio station WEEI, via ESPN.
"We can't make any mistakes or give them any opportunities. If we have plays that are there to be made, then I've got to throw it and hit it. We've got to come up with them.
"We're not winning by 30 points. Every game comes down to the end. We've just got to do a better job when we have opportunities as a team in all three phases to make plays to help us secure wins."
