For someone going through his first NBA postseason game as a head coach, Tyronn Lue had quite a successful day on Sunday. Playing a Detroit Pistons team which was surprisingly shooting the lights out from distance, Lue helped guide the Cleveland Cavaliers to a Game 1 victory yesterday afternoon.

When it comes to Lue’s performance, it was definitely a mixed bag of good and bad. His decision to go small and play Kevin Love at center in the fourth quarter was huge, as it played a crucial role in Cleveland pulling off a win.

However, one thing Lue definitely needs to work on his is in-game rotations. While the aforementioned example was a great call, others Lue made throughout the game were head-scratchers. For the Cavs to make a deep playoff run, their coach is going to need better rotations from here on out.

For one, Lue has to find a way to get LeBron James more rest. Cleveland’s superstar played all but eight minutes yesterday. While James claims he’s feeling much better physically coming into the postseason this year than he did last time around, playing him 41 minutes a night is a quick way to ruin this.

The issue Lue seemed to run into when it came to trying to rest James was the fact that none of his other lineups seemed to score consistently. This is the kind of thing that happens when Matthew Dellavedova, Tristan Thompson, Richard Jefferson, Iman Shumpert and Timofey Mozgov are all sharing the court at the same time. While Jefferson and Dellavedova each had their share of impact shots, when there’s nobody on the floor who can create their own offense, opponents are going to easily take advantage.

Lue also has to figure out what to do when it comes to backing up his frontcourt. With Love and Thompson getting heavy minutes, Lue struggled with finding capable bench replacements. When Mozgov was on the court, he was once again the liability he’s been all season long. In just five minutes of action, Mozgov generated a plus/minus rating of minus-5.

One would think that, since Mozgov is completely unreliable right now, this would mean more minutes for Channing Frye, Cleveland’s trade deadline acquisition.

However, this is another issue Lue ran into. Frye didn’t play a single minute yesterday, much to the chagrin of numerous Cavs fans venting their frustration on Twitter.

It’s just one game, sure, but if you need a backup big-man, why refuse to let Frye even take off his warmups? He’s proven to be effective more often than not coming off the bench, and yesterday seemed like a game he would’ve thrived in. Unfortunately, Frye spent Sunday glued to the bench.

While the aforementioned issues didn’t impact the overall result of Game 1, they’ll become more significant if not addressed from here on out. Heavy minutes eventually took a toll on James last postseason, while minimal help from bench players will always have a negative effect on playoff games.

At the end of the day, it was Lue’s first playoff game, one of many which are surrounded by huge expectations. You can’t spend too much time grinding your teeth about questionable decisions.

That said, Lue has to make better rotations from here on out. The decisions he made yesterday may not result in losses during the first round, but the deeper Cleveland goes, the more likely shoddy rotations start to become a hindrance.
