All three who got in,deserve it. As for Biggio and Morris they probably should be in too,but the problem is the fact that there were too many first timers on the ballot that could have taken away some of the votes that they may have received. Also Jones,Rogers and Benitez receiving votes may have prevented Biggio as he was two votes short,but we probably will never know. Also Raffi Palmerio is off the ballot next year as he didn't receive 5 percent of the vote (4.4) and Sammy Sosa only got 7 percent.
That being said,the baseball hall of fame is by far the hardest to get into mainly because things like the number of batting titles,MVP awards and all star game appearances don't count for all that much to the voters,because if that were true Biggio and Dale Murphy would be in by now.
