As an academic, used to rigour in writing, I'm surprised you would use such an unqualified form of words here. If it were me, rather than 'clearly there was no collusion...' I'd feel more comfortable arguing that 'there was insufficient evidence to prove collusion...'.I have a problem with the 'clearly' and with the 'no collusion', just to spell it out.
It's not a trivial or pedantic point. A large part of the Mueller report relates to the obstruction of justice, where the report seems (I haven't read it in forensic detail) pretty unequivocal that obstruction took place, and there is enough evidence to prosecute a case. So, on the one hand, we have proof of obstruction, and on the other we have insufficient proof of collusion. Your claim ('there was clearly no collusion') doesn't admit the possibility that the 'insufficient proof' derives from the 'obstruction'. So I'd give you a C for this, sorry.
