While I agree with BDeCosta, Evantime, and the others who say that what happens this season could very well have an important impact on what the future of this team looks like, it's not really the main reason that I'm engaged with this team.
The main reason I'm so engaged with this year's team is that I find them to be very exciting to watch right now.
They are a team devoid of superstars with a gritty, defensive identity. So far they look like this formula is going to keep them in the playoff hunt in the improved East all season long.
They're fun, they're exciting, they're tough as nails. They seem to know that ultimately their success depends on effort and unity.
All in. I'll worry about the future in June. Right now it's all about the 2015-2016 Celtics for me.
