Gaff has got good leg speed.I don,t think Polec tested at the draft camp but by reports he is quick.Tough decision but I will be happy with either.Personally I would like us to take Parker over Conca but the "go home" factor may get Conca over the line.
Also, I think West Coast should gamble and go with Polec to gain some leg speed. Masten, Shuey, Priddis, Ebert, Stevens aren't exactley line breakers. Take a gamble. Freo gambled with Hill and Fyfe and they have paid fantastic dividends
