Well I think everyone can agree that both Raekwon McMillan and Kiko Alonso are horrible in pass coverage. The hope is that this system helps them play to there strengths. For Kiko, he is our best takeaway producer at the LB spot that we've had in the last 30 years. If turnovers win games … he's extremely valuable as a guy who generates and converts takeaways. IMHO, that's by far the biggest impact a LB can have on a game, and one that Kiko's detractors always seem to conveniently ignore. As stats go, takeaways is one of the very most important ones. Talk about sacks, tackles for losses, number of tackles, etc., etc., etc., but one takeaway is worth 3 sacks. If your defense doesn't have people who can generate takeaways, then your defense is bad.
Eventually every player is replaced. Not sure when Kiko's time will come, but when it does, the team needs to have an answer for those takeaways. Because without them, our effectiveness goes down significantly.
