Notice the trend? It is absolutely going to someday make a full-on comeback. 

Bullpen Carts may finally be a thing again for the first time since the 1970's and 1980's. Two teams (D-Backs and Tigers) have already implemented the carts, and now a third team may soon be following.​

​​​It all started with Arizona. Then Detroit followed suit. Now Boston is next in line.

Red Sox president Sam Kennedy ruled it out for the 2018 season. Probably in an attempt to see how much popularity it gets in Arizona and Detroit.

If that's the case, things aren't looking good so far. ​The D-Backs refused to use it on Opening Day. Bummer.

Fans from all over the country would love to see this. It would bring the older crowd back to the times when they were young and watching baseball, and it would allow all those funny videos the younger crowds have seen become a reality.

This would really be awesome if it works out.
