The answer to this question is determined by whether or not you believe in learning curves. JP is just now at the bottom of the curve. POTENTIAL indicates he will not stay at the bottom. The unknowable is the steepness of the curve representing JP's progress. The journey from kid QB to polished veteran does not go through the bench. Therefore, I predict JP will not be pulled under any circumstances other than a complete blowout or injury, for the entire season.
In other words, in the NFL, long-term gain should more important than short-sightedness, but it doesn't always work out that way there or in the business world in general.
