I think he meant. Preseason shine for Mannion.
I think S.M. is an accurate short to medium passer can read zone D , is a smart coach's son who has ability to pick up an offence very quick and is good enough to be a short relief starter in the league.
I think he could look very good in this offence and become a quality back-up.
There might have been s slight reach at round 3 that's true.
I don't see Mannion being on the level of a A.J.McCarron who would have more cred around the league but it doesn't mean Mannion can't live up to value of his selection.
QBs are often over drafted anyway.
