The Boston Celtics are good. Really good. They have one of the NBA's best records, their offense is cooking, their defense is improving and they are set to get Gordon Hayward back from his fractured hand sometime within the next few weeks.

But it's still pretty clear that the Celtics need more.

While Boston has a ton of talent, it is pretty top-heavy, and in the playoffs, that can be exposed.

The good news is that the C's have plenty of time between now and February to bolster their roster.

So, here are a couple of players who would be perfect trade targets for the Celtics:

Willie Cauley-Stein

The area where the Celtics need the most help is in their frontcourt.

Enes Kanter and Daniel Theis are very solid rotational players and Robert Williams looks like a stud in the making, but Kanter is a defensive liability, Theis is inconsistent (and injury-prone) and Williams remains very unproven.

Enter Willie Cauley-Stein, who is currently playing for the Golden State Warriors but seems like a rather prime trade candidate with the Warriors plummeting to the bottom of the standings.

The catch for Boston is that it is going to have a tough time matching salaries based on its roster construction, but Cauley-Stein happens to be a rather realistic target given the fact that he is making just $2.2 million this season.

The C's can certainly put together a package (maybe something like Semi Ojeleye and a second-round pick) to get the Warriors to bite (if they are willing to trade Cauley-Stein, that is).

Cauley-Stein isn't great, but he would provide the Celtics with some much-needed depth up front and would give them another big who can guard the likes of Joel Embiid, Marc Gasol, etc.

Noah Vonleh

Part of me says there has to be a reason why Noah Vonleh can't seem to stick with a team. Another part of me says that he is a big body with some athleticism that will come cheap and provide Boston with a lift up front.

Vonleh is making just $2 million this season and is on a one-year deal, so the C's wouldn't be held to any sort of future commitment to him if they acquire him.

He also isn't getting much playing time for the Minnesota Timberwolves, so you have to think the Timberwolves will be fairly amenable to trading him, especially if they fall out of the playoff race between now and February.

Vonleh actually had a really solid year for the New York Knicks last season, averaging 8.4 points and 7.8 rebounds per game while shooting 47 percent from the floor. He even started to extend his range a little bit, making 46 three-pointers on the year.

If he can come to the Celtics and give them that type of production, it would be pretty significant.

Again, because it will have difficulty matching salaries, Boston is somewhat limited in what it can acquire, barring some sort of out-of-nowhere blockbuster (which almost surely won't happen).

Based on what could potentially be available, Vonleh is a name the C's should certainly monitor.
