This will be a shot post since the set didn't had only on insert set, no parallels and no subsets.
There aren't many notable players from this set. The top players are, in addition to Sizemore, Pat Burrell, Barry Zito, Adam Wainwright, Adrian Gonzalez, and Mark Buehrle. Your opinions, of course, may differ.
Most of the 110 players in the set had been drafted in 1999 or 2000. Some of them had already had their major league debut. These players had their debut date stamped on the card in silver foil. But there were some players who had a date of 00/00/00, like this one.
I bought a hobby box of this at the time which included the entire set. Each box came with one auto. There were 60 autos available.
There was also available a complete chrome parallel set. I only have one of these which I must have found in a repack.
Boxes of both these sets are readily available on eBay. Here's a link to the checklist at baseballcardpedia.com.
