Mk…you might want to consider mixing in some plyometrics as well to improve your explosion to the ball. The only reason I suggest this is that you mention that you have good vision but “can’t make the play”. Instinct, which is somewhat intangible, obviously plays a big part as well, but if you have good vision, combined with good instincts AND good explosion, you’ll get to the ball.
Consider some of the best LBs in college (AJ Hawk-OSU, Paul Posluszny-PSU) and the NFL (Zach Thomas, Brian Urlacher)…These guys obviously have great instinct and ability to anticipate, but once they recognize where the play is going, they are there in the blink of an eye. Plyo work might help you out here. Just my .02. Best of luck to you.
