The Dolphins are simply hedging their bets here and don’t want to waste time in waiting for answers from anyone. The move to bring in Smith is not just to cover themselves, but to possibly get a decision out of Flynn.
The team should be careful though and not let Flynn get to far out. Smith did have a great run last year but it was merely not because of his skills alone. The 49ers defense, who were ranked #1 last season, was the main reason the team did so well.
The Dolphins can’t risk to go through another quarterback experiment like they have in recent years. Current quarterback Matt Moore was thought to be the answer to former quarterback Chad Henne, but Moore has yet to deliver.
