Please. No platoon system. Instead what is needed is an open competition for the starting QB.
Here's how I see it working out. Because of personal relationship with JT, Meyer will not 'personally' demote him. But, assuming Wilson is coming in, Meyer can defer to him. Since he's the new O Coordinator, let Wilson decide whether he is ok with being the 'bad cop.' If I were the new O Coordinator who was brought in to revamp a stale offence, I would want everything on the table. Deference and respect should be accorded JT, however I would want to re-evaluate all the personnel available to me. Absent someone like a Watson, I would insist on an open competition for the QB slot.
