The NFL Players Association urged rookies to wait before making big purchases during their rookie symposium in Florida on Tuesday. The 90-minute seminar on financial management stressed that players be especially prudent in their early spending. The NFL lockout has kept rookies from signing contracts with the teams that drafted them in April. Karl McDonnell, the chief operating officer of Strayer University, said before the meeting that rookies would be told to "take a year off from making any big financial decisions."
