Shelvin Mack wants to get a feel of the NBA draft

The Butler Bulldog's junior Shelvin Mack annonunced that he would try out the NBA draft to see where he would stand.  He does not have an agent helping him with the process because he said if it does not work out in the NBA then he wants to go back to Butler and continue playing with them.  The reason why he is still eligible to play in the NCAA is because he made the smart decision of not hiring an agent. All players have to officially declare their intentions of being in the draft on April 24.  They have the option of withdrawing by May 8th at the latest.  Critics have critiqued his percentages in being that his shooting has decreased slightly despite the fact that they still believe he will be a second round draft pick.  I think that Mack should stay for his senior year and finish the rest of his education considering it is only one more year.  Do you think that Mack should complete his senior year with Butler ?  Or do you think he should take his chances with the NBA?
