Who Would You Collect…?

We all have our favorite's who we collect and there are plenty of reasons for those favorites. Sometimes it's a hometown player or a legend who brings back fond memories. However, there are certainly players who are at the top of the hobby that everyone would like to collect, but their cards/memorabilia might be out of reach for some collectors including this one. I thoroughly enjoy collecting cards, posters and kicks from my favorite players, but I also wouldn't mind adding an Upper Deck Exquisite or Panini National Treasures RC of Mr. Blake Griffin to my collection. They're about $1,000 out of my price range, but this did give me a good idea for a blog question. More specifically, what young/rookie player at the top of the hobby world right now would you start collecting regardless of finances?
