This is kinda where I'm at. On the one hand I think Kliff is a ball and chain that in some areas is holding Kyler back (transparent scheme, too much short, poor route designs etc etc) but on the other hand I think Kliff thought he was getting more from Kyler from day 1 and there's been some holes in Kyler's game Kliff wasn't expecting.
Kyler makes me think of an athlete in the Decathlon. He amazing at the 100m, Javelin, 400m, and Long Jump. He's ok at the shot put, 110 Hurdles and pole vault but absolute garbage at the discus, high jump and 1500 metres.
We all spend a lot of time glossing over the thing's he's really bad at that are holding the team back (Intermediate throws, YPA, scrambling out of bounds for losses, not stepping up in the pocket, 3rd down passes, passes inside our own 20, reading defenses etc) and focus on the stats he racks up with the things he's good at.
Some blame on both sides here but overall I'd say Kliff is holding Kyler back more than the other way around.
