I really hope he is. Attributes are great, but players differentiate themselves from others by more than just a handful of basic attributes.
My biggest fear with this system is that Player A is Player B is Player C with maybe one different ability and the players begin to feel like "specialized clones" instead of individual players.
While I'm not convinced this is a better or worse system, to me the logic behind numbers made sense to me. The problem may have been that they weren't used effectivly.
A number for speed makes sense if based on some sort scale. A 99 Speed is a 4.2 40, a 90 Speed is a 4.3 40, a 80 Speed is a 4.4 40, etc. And every fraction of a second is somewhere in between. The new system feels like "Gold Speedster" is one speed, "Silver Speedster" is another and nobody runs in between. So if you had 10 guys racing (5 gold and 5 silver) all 5 golds would finish at the same time, all 5 silver would finish at the same time. The same would happen with 5 99's and 5 90-'s, but at least there is the ability to be slightly slower at a 98 or a 97, which would be the difference of winning a race by a small margin.
And while numbers might not make sense in all categories, I think they make sense in most (running speed, jumping ability, throwing strength or accuracy, etc) as they can be based on some scale that is then programmed into the game to reach results. Maybe I'm just so used to it, that it's all I know. But the logic makes sense. The actual numbers can be based on and scaled to statistics, where as the new one could, but it seems like it's just based on opinions of players (he was clutch in his career, so he gets a blanket "Clutch" rating. And if they are based on stat's, then the scale appears too be much to broad with out enough "inbetween" area where either a player is fast, average or slow and not kind of fast or slightly above average, etc.
