I think Barlaser can, I think he's the best passer of the ball we have, especially the more difficult passes or at least he has the best vision for them. I think he's fine in possession too, when we have some options, but we seem very slow at creating triangles etc. A key flaw for me is we lose momentum when someone fluffs a 15 yard pass, either passing to their weaker side, the trouble side, or passing behind them. The players passing the ball should be enabling the next guy to make a first time pass, but we fail this so many times, so they end up having to roll it back, or we just lose all momentum we had.
I don't rate O'Brien at all, but willing to give him time.
