Was one of the reasons I wanted to see Keefe be patient with Robertson to see if he's ready sooner rather than later. They may as well just send him down at this point. Playing him 8-9 minutes a game, gluing him to the bench every time he has a bad shift and then sending him to the press box after gluing him to the bench. Doesn't do him any good at all. Play him or send him down, why do coaches do this shit to young players over and over and over because it's too risky but will happily let anyone with 500 games played in the league cost them their job?
ZAR has been pretty shit (45% xG) but gud pro, knows where to stand, so he plays. Jarnkrok has been fucking unplayable (39.6% xG)...but gud pro, knows where to stand...so he plays. Robertson has not been good either (47.5% xG) but has matched Jarnkrok's offensive output in 8 less games. Can't be patient with his rookie fumblefuckery for reasons though.
If Robertson isn't the answer (how the fuck would we know?) then Keefe better hope that the 3 you mentioned pulled their heads out of their asses because yeah, the left side is a train wreck right now.
