Was /u/RexLego actually Chris Wallace?

We know that at least one NBA executive covertly used social media to further a personal agenda. Talking heads on sports radio say "it happens all the time." Enter u/RexLego, a user whose sole purpose has been to defend the Grizzlies GM on this sub.

A quick look at his post history shows that he gives Wallace a 5 star rating as a GM, a two part post saying for fans to stop blaming Chris Wallace, and a large argument with me about how a broken clock is correct thousands of times more often than our fat stumbling manbaby.

Then suddenly at the end of the season, when presumably a General Manager's workload become more busy....he vanishes.

I think that it's most likely a toll account, but it there is precedent that u/RexLego could in fact be Wallace himself

Edit: If that is the case this seems to be his first post on reddit:

Hi, i'm a hardcore Grizz fan and I don't want Wallace gone. Pera is the bigger issue.

Edit numero dos: shout to u/masterofmustaches for being the first to break this on twitter
