I generally like Doyle's analysis, but that's a ridiculous statement. Diego Fagundez is not a question mark. Luis Caicedo is not a question mark. Edgar Castillo is not a question mark.
It is hard to know which player should, or should not, be a question mark when they all are in the shadow cast by the biggest question mark on the team: The Manager.
That works both ways, though. Personally, I have a hard time definitively pointing the finger at Friedel (...and/or Heaps) given how bad the talent level has been.
I'd argue that with the exception of Castillo those are still question marks. By all accounts Fagundez should be the best RW on the roster and Caicedo looks like he should be a lock for the ball winning 6, but neither have been consistent enough to really preempt any arguement. In reality Gil, Penilla, and Castillo are probably the only players on the Revs who other teams (probably 50% of the league) would be happy to have start for them
