Ricky is certainly not NFL-ready now. But how many of his "flaws" are his own and how many are because of the coaching he has received along the way? You never saw him fire bullets at receivers but was he coached to do that (or not coached enough to throw "on the rope")? Did anyone on the staff really work with him on his progression and speed of release? Or did they more work with him on routes, receivers, directing the offense?
I think Ricky has many strengths that could make him successful in the NFL -- poise, character, leadership qualities, commitment, long hours learning playbooks and studying game film, vision, physical size, adequate mobility, toughness. By all accounts he is a highly "coachable" team player who works well with a coaching staff. You never saw him pouting on the sidelines, arguing with a coach, hanging his head.
Working with a good position coach for a year or two and alongside a successful signal-caller, can Ricky develop into a top caliber quarterback in the NFL? My gut says yes.
