Show me a report from this time last year questioning his arm strength. How do many experts (this time last year), call him the number one overall QB for 2013 and possibly the number one overall pick with questionable arm strength? Makes no sense. The arm strength issue came up this year. And he got hurt. Shoulder.
His 64.1% 4 year completion percentage says that you are not correct in his accuracy from 15-30 yards. Remember he started as a true freshman.
But you really dont know much about him and we know this.
