Based on this
His last assist was 2 months ago mate. Since then he's had 73 cross attempts over 6 games, and only 4 finding a Rangers player and 0 assists. That's the poorest conversion rate in our team by a distance.
Stats can be made to look anyway you like - that cross conversion can both be his fault (which it will be on occasions) and equal the fault of those he is crossing the ball to.
Similar to a passing percentage if you play 5 yard passes all day left / right and back everyday your pass completion will be 90% plus but if it does nothing for your team in an attacking sense it’s a pointless metric.
Happy to concede Tav has not been at his best this season but he is fairly far down the pecking order of who is to blame for our performances thus far IMHO.
