People are so flippin sensitive. Michael is a fine rb, but he IS NOT the style of runner we are constantly told is they want. He is better as a change of pace back
Here's a scouting report from when he was in the draft.
2013 NFL Draft Profile: Christine Michael
ANALYSIS
STRENGTHS
Low center of gravity back with good thickness throughout his frame to take and give out punishment. North-south runner who uses his strong legs to burst out of the hole to eat up six or seven yards in a hurry. More speed in the open field than youd expect given his size, sets up defenders in the open field for a dangerous cut on the run. Capable of strong cuts on stretch plays, runs with lean and balance to blast or step through arm tackles near the line. Also willing to spin off tackles to free himself in space or stretch for an extra yard inside. Takes out blitzers with cut blocks in pass protection, also defenders at the second level as a lead blocker.
WEAKNESSES
Missed the end of both his sophomore and junior seasons due to injury. Not elite in his change of direction ability, will round some cuts and gets tripped up trying to change field. Will spin away from situations instead of taking what he can get. Ball security can be an issue, will run with the ball away from his frame (three fumbles in 2011). Not often targeted in the passing game, must prove he can be a reliable receiver. Whiffs too often when trying to land a punch in pass protection, and gets pushed back too easily when man-up.
Seems pretty accurate scouting report IMO. Michael isn't that punishing runner type, like Lynch and Rawls, but his style should work good with the zone run blocking scheme and that's what matters.
