The Briton fell heavily twice on Friday - including a 293km/h off that damaged his forearm – and again in Sunday's warm-up.
He says that all three incidents affected his race performance, robbing him of confidence but more importantly derailing preparatory work and leaving the team scrambling for set-up ideas.
"What went wrong was that I crashed on Saturday morning," Crutchlow said after finishing a distant seventh. "What went wrong was we were too indecisive about fuel tanks. A lot went wrong.
"Ultimately I never performed. I don't make excuses, I had a bad weekend.
"I crashed, my arm is a mess, so I was unable to brake they way I wanted.
"On Friday we were top three; qualifying we were top three. I know I can go fast around this place.
"In the race I was riding around unable to do anything, [we] had no bike set-up over the weekend and no confidence in the race. That's not like me at all."
'WE NEED TO REGROUP'
Crutchlow said a poor run of form coming into Silverstone – he finished outside the top four in both US races and crashed early on in the Czech GP – also contributed to his malaise at Silverstone.
"I had a bad run leading up to this race. Indy we were miles off, Brno we crashed and here we topped it off - I was not wanting to crash, I needed to finish," he said.
"We need to go away and regroup.
"If I was fully fit and hadn't crashed, I believe I could have been towards the podium – towards the podium - but I'm not one to say 'shoulda coulda woulda'.
"No matter the circumstances that was where I finished and that's it. The other guys did a better job than me over the weekend."
