he showed his youth and inexperience for sure... he stands totally flat footed at times in the pocket- like a statue still, i mean... arm cocked, looking downfield and totally unaware of what's happening around him... easy pickin's for a closing defender as he has to 'start' moving, and that first step betrays his intended direction, making him a simple target to clear.
my personal opinion is that he demonstrates good raw talent- and has a good basis to work with going forward. he just needs to be coached up to the level required.
