So, here's the karma part. Why didn't McPherson make it in the NFL? Lack of talent? Well, we don't really know, because he didn't get on the field much during preseason. Why not, you ask? The press release tells you all you need to know:
The Saints also cut fourth quarterback Adrian McPherson, who was
injured when a mascot hit him with a golf cart in the Saints' opening preseason
game in Tennessee.
