Speed includes reaction time and agility not just foot speed. There a several players who need some serious off-season development that way. From my amateur perspective their bio-mechanics need some real training to improve their "speed".
I've seen plenty of videos on social media of athletes like Hatch, Colohan, Bailey and Sine getting training along these lines. Walbruch's rehab videos are exactly what I wish for. JP would be a fantastic investment for this team and I'm sure he could tailor the training for soccer.
In the hope for next year category this is something I'd hope will happen. Wishful thinking perhaps.
