What he's seen after five games with his new franchise has been something entirely different. The Nets are 0-3 away from Barclays Center, with road losses to the Cleveland Cavaliers, Orlando Magic and Washington Wizards.
But he's not regretting his decision just yet. He told Stefan Bondy of the New York Daily News that this team needs time to find its collective rhythm.
"Obviously it’s a process," Garnett said. "It’s not an easy process trying to figure it out. (Some) nights it looks great. Some nights it looks like tonight: pure crap.”
This is the first (and hopefully the last) time I have ever raised this question, but what exactly qualifies as being "pure crap"?
Try blowing an 11-point lead in the final 4:27 of regulation to a playoff-hopeful Wizards team that entered Friday night's game just 1-3 on the season. Or Garnett shooting just 2-of-11 from the field, while his post counterpart Nene scored 20 points on 8-of-12 shooting.
No one expected this Nets team to figure it out on opening night. Not with Deron Williams missing all but one preseason game with a sprained ankle and first-year head coach Jason Kidd starting his season by serving a two-game suspension.
But no one was willing to give this team a lengthy championship window, either. Not even the man who put this team together, Nets general manager Billy King.
"Now, this is the window -- this season," the executive told reporters at the start of training camp, via ESPN New York's Ohm Youngmisuk. "We're going to see what we can do with this season, and then we'll see what next season brings."
With no starters under the age of 25 and only one younger than 29 (Brook Lopez), patience isn't a virtue for the Nets; it's a potential problem.
There are only so many bad losses that can be swept under the rug before that pile becomes big enough to topple Brooklyn's title hopes.
Assuming, of course, there is actually a road from pure crap to the championship podium in existence.
