Because I think he'll be good enough in the playoffs to make up for it. Let me clarify along with what I said above.
I think Neal was a better compliment to Geno in full throttle. If a team couldn't handle Geno, Neal was a better triggerman for him than kessel ever will be. In the regular season, you play a lot more games where Geno can do that, so Neal was incredibly effective in the regular season. But when you can slow Geno down, Neal was doubly slowed down. In the playoffs, Geno is more likely to be slowed down, and thus Neal wasnt very effective for us in the playoffs. When he did, it was in bursts in those games Geno could dominate.
With kessel, I don't think he is as effective as Neal with full throttle Geno. The lack of one timer is the issue. But honestly, I don't care. In those games, we generally can win with a bit less effective wing. But when Geno slows down I think kessel can keep on scoring. In a playoff series, slowing Geno down will be a huge risk now because it probably means they don't cover kessel as well as they should. And as we've seen, kessel and hagelin are dangerous without Geno being involved at all. That's something we haven't had with sid or Geno since hossa. And I think it's more valuable than 10 or 15 regular season goals.
I also think kessel will improve in the regular season, but that's a different point altogether.
