Cease's velocity is down so far and he only had 2 swings and misses the first time through the order. The results are good, but this usually isn't the norm with him.
He's also not even fast. He's 17th percentile in sprint speed. His true top speed is probably much better than that, but it seems like he goes first to third more than anyone else on the team.
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).
