Hindsight is wonderful.
Questionable positioning and overall bit average defending plus consistency has generally his flaws in his career, while generally showing overall promising qualities as a full back, mainly going forward and being quite dynamic type of player (generally was a decent cheap squad player pickup).
If he had been this god forsaken awful (not average defending, but AWFUL) as he has been for us throughout his career, he wouldnt have been in Azzurri, played in Roma and now in Juve. So yeah, as I said, hindsight is wonderful, especially when you are talking about a 3 months period in someone's overall (still young) career.
