You don't necessarily have to do it now, but at some point you need to make some trades if this continues. I had a team last year that had what I honestly think may be the best pitching staff of all time, but relatively weak hitting. I won ever single pitching category, and stayed near the middle of the pack in hitting. The entire season I flirted with the lead, but at the end I needed a few more points to put me over the top, and the only place I could gain anything was hitting. Unfortunately, my hitting just wasn't good enough to gain much ground and I ended up losing the league narrowly.
