Hw much is Wade being paid? Is it worth it to him to stay?
I don't know how much he was making playing rugby, but it a pretty popular sport, so they must make decent money. Why would he waste prime years of his career, relegated to a NFL practice squad?
All this stuff about him having to learn how to pass protect seems a bit overstated. Every year there are rookie RB's that haven't done much blocking. Most seem to be able to adapt to an acceptable level. I think his main concerns are with being able to catch the ball, and running routes out of the backfield.
This stuff isn't rocket science. There have been plenty of utter idiots that have played NFL football successfully, especially RB.
