You seem to be under the misassumption that feelings don't matter, so let me pose a hypothetical to you. At your place of employment you have two bosses who alternate days. One is friendly, genuinely cares about you, and manages you as a person, and not just an employee. The other is bossy, doesn't seek your input, and is only interested in doign things his way, not matter what anyone else thinks. Which one of these bosses would you rather work for, and which one would get the best effort from you? Also, from a statistical standpoint, last year Span's UZR/150 in CF was 17.6. In the last 4 years, he's gone from -32.7 to -11.5 to 4.5 to that 17.6--in other words, he has vastly improved his defense over the past 4 years. Revere, meanwhile, was at 15.1 in CF for UZR/150 last year. Denard therefore, based on the extremely small sample size, is more valuable in center than Revere.
