I doubt TLR was suppressing the team's power. Maybe the guys are playing more loose without him in the dugout, but I doubt they all just got their power back when he went away.
Eloy has actually been pretty good when he's been able to play this year. Maybe you can sell a team to take him on the results alone and maybe they'll just think our training staff sucks (which is true).
Announcers who are just out of the league and played with some of the guys in the games they're broadcasting tend to talk positively about said players. Chris Young did the same thing talking about his ex Boston teammates during the Apple TV broadcasts.
