9 Glaring offseason regrets Mavericks have after first month of season

The Dallas Mavericks are sitting at 11-8 through 19 games of the NBA season and are coming off an unbelievable loss on Saturday night.

Dallas went on a dazzling 30-0 run to get back into the game but ended up losing 126-20 to the Oklahoma City Thunder. Dereck Lively II had the best game of his career in this game, as he finished with 20 points, 16 rebounds, and seven blocks.

Even though Dallas has gotten out to a solid start, there are still some things that could have gone better during the offseason.

9 Glaring offseason regrets Mavericks have after first month of season

It's obviously hard to predict how a player will play during the regular season or how a new signing will fit, but there could be some regrets that the Mavs have from the offseason.

Here are eight glaring regrets that the Mavs have from the offseason.

9. Not signing a back-up rim protector

One of the brightest spots of the Mavs this season is having a solid starting center. Dallas has been without a great starting center for many years but struck gold in the draft by selecting Lively II.

Even though Lively II has been great for Dallas, things have gone poorly when Lively II is out of the game or misses the game completely. There is a massive dropoff when Lively II is off the floor, and Richaun Holmes or Maxi Kleber is on the floor.

This is why Dallas likely regrets not signing a backup rim protector during free agency.

This would allow Dallas to not have to lean on Lively II so much and allow Jason Kidd to have him on the bench for an extended period of time without having to worry about the other team dominating inside.

There weren't necessarily tons of options out there for Dallas to add a backup big, but that is arguably one of their biggest weaknesses right now.

This shows how great Lively II has been but also shows how bad Dallas' bigs off the bench have played. Holmes has been better over the last few games, but an upgrade there is ideal.
