Keenum's offense was ineffective on third downs, leading to a series of three-and-outs. His one bugaboo has been reading the blitz.
The decision to change quarterbacks is still a peculiar one. Keenum's passer rating, yards-per-attempt average and touchdown-to-interception ratio blow Schaub's figures out of the water.
From what we have seen this season, Keenum has a chance to develop into the Texans' long-term solution at quarterback. Schaub does not.
This is the type of panic move that could cause a coach on the hot seat to lose support in the locker room as well as the front office.
