the fatal mistake this regime has made with suckchez is they have fallen in love with his potential and are not seeing reality.
He does have the physical ability to make all the NFL throws, he can fit the ball into tight windows at times, and he has adequate mobility. HOWEVER, he is inconsistent with his mechanics, leading to many bad throws, he cannot read a defense, has poor pocket presence and terrible touch on his passes. He has been a 4yr starter and has shown little to no improvement. Due to the financial committment they are stuck.
The end result will eventually be what we want though. Either suckchez will improve (doubtful) or tanny and/or the rex the buffoon will be fired
