He is their first opportunity to find a successor to Stafford. There will be more opportunities next year and in the future until they find their guy. They just started a year early. And no, I do not think he will be their starter in the future. He will take time more time to develop than McVay has to win another SB.
I hope we follow their lead in next year's draft and start stacking up 1st round qb's until 1 hits.
