Hello.
Pre-season games are notorious for their mirages, masking the true nature of the team and certain players. From what I've watched last night, all quarterbacks seemed to do all right, but really didn't set themselves apart from the pack. Brock Berlin surprised me with his moxie and ability, but that was against 3rd & 4th string defenses.
In today's Herald, Armando Salguero stated that Gus Ferrotte is scheduled to start next week, so things should be interesting. It would prove telling in this QB competition as to how Gus would do with the 1st offensive unit against the opposing team's 1st defensive unit.
Either way, I think that the winner of this QB competition would probably not do well, and would not help the Dolphins win that many games (8+) this year. I have a feeling that by next season, the Dolphins braintrust will eventually acquire a starting-caliber quarterback either through the draft or free agency.
Enjoy.
