Totally different teams and thus expectations of the two QB's.
Skinner had a defense on the other side of the ball that was pure NFL. heck, the 2006 team just had to run and not turn it over. In 2009 when that talent was basically gone, Skinner showed his true passing skills which were considerable but it was the first season Lobo had to orient an entire offense around the pass.
Price was brought in to pass the ball, not take care of it so the defense can score as needed (an exaggeration). Price is excellent as was Riley. Time will tell but I am thrilled with Price now as I was with Skinner then.
