As center you have to cover BOTH sides, the middle, all who drive hard down the lane, high post, center post, rebounders who pound you, high and low, guys who sky in for the rebound..as a forward, you cover mostly your side, to the baseline. I played forward for almost 20 years..with a decent amount of center, in terms of years also..ask around with guys who had played center, it is like the goalie in hockey...in the end all the shots come to YOU..even when the forward misses his guy..it comes to you...Hey, try playing center...you'll see..!
