FFS - trading for a super toolsy player like Derek Fisher should not be viewed as a negative. That's how you land guys like Teo (which Atkins also did). It's a high risk/high reward move. Those moves are going to fail more than they succeed. You want to rip on him for trading for Brandon Drury? yeah, OK, go for it. The guy's shown over the past couple of years exactly why Atkins wanted him. It just didn't happen for him in Toronto and there are all kinds of reasons that may have happened. Players don't always breakout when you want and can struggle when moving into a new environment. Varsho's a good example of that right now.
Like all GM's, there have been trades that have worked out and trades that have flopped. Atkins has made small moves that worked out great (Teo, Espinal), he's made some big splashes that have worked out too (Chapman, Berrios and potentially Varsho). He's also made some stinkers.
In all reality, it seems unlikely they will actually start a full blown rebuild this year. We could see some pieces moved at the deadline (Kikucci, Jansen, Yimi, etc.), but it seems highly unlikely they'll be making any franchise altering moves. A new GM will be brought in this offseason and that's when we'll see larger moves made.
