No doubt! Zatsiorsky discusses that EXACT issue in his book Science and Practice of Strength Training... in the beginning, when strength is a limiting factor, increasing strength will lead to a direct increase in sporting performance. But once you have reach the level of strength required to perform optimally in your activity (which varies depending on your sport) even great strength gains lead only to marginal performance increases and the best way to keep improving is to increase explosiveness/power.
A while ago the university of Nebraska found that the strongest players on their football teams (squat and bench results) were the backups (often 3rd stringers) and the starters had better results in the power clean and vertical jump.
Do not drop strength work though, you want to at least maintain the levels you have right now.
