Back on topic:
More important than trailing the leader by 4,900 points is how many points are you trailing the last team projected to make the cut and how close is he to locking.
If he will lock before the offseason AND you can get to within 2,000 points of the last team that made the cut you should absolutely go after him (as long as you'll still be able to schedule a visit. If he has 5 visits set up than fugedaboutit). Once he locks you can use a lockpick and you'll leap into 2nd or 3rd place and will likely only trail by about 300-400.
