2008 would mark the third year for Topps mid-high end brand. The base cards were still serial numbered and the inserts still all looked the same. I guess that's the one constant through the years with triple threads. Relics and autograph cards still all kind of look the same.
Still the Triple Threads base cards are fun to chase down and collect. They don't number the base cards anymore and I would suspect that eventually Topps will just do away with the base set.
