I've written in various places, and Brian said again just yesterday, that Blake Countess is a very good zone cornerback who was exposed last year by being asked to do things outside of his comfort zone. Or outside his natural abilities. Or outside the capabilities of a guy his size.
The tape is the best evidence that he's not a fit for the aggressive man-to-man stuff Michigan switched to early last season, and will almost certainly try again this year. The best evidence against it was produced by Countess this spring, when he generated above the usual level of comments for controllable things like his work ethic, his knowledge of the defense, his toughness, etc.
But his size is a thing Blake can't change, and that plus the inability to shut down Tyler Lockett or William Fuller downgraded our hopes for a next-Woodson (leave him on an island) ceiling even before we discovered he's no MC5:
(you forgot to kick out the jams.)
That kind of thing can be mitigated by not lining him up so close—you give up that lock-down mentality for either soft coverage that lets the QB complete short stuff, or puts a safety over the top so Countess can break on that stuff.
Is Countess too small?
His size is below average for a guy who registered a play on a Power 5 roster, though not debilitatingly so. Here's how the CB depth chart stacks up against cornerbacks on all Power 5 rosters from 2010-2013 (#6 is Lyons):
Bubble size is more guys with that listed ht/wt. Avg height was 5'11", and weight was 183. Year-to-year differences were negligible.
If you need a roster refresher I put the tentative depth chart below-right. Our guys are generally on the line of distribution, with Richardson a wee little dude and Stribling and Dawson (and Keith Washington) on the edges of lankiness. I included Peppers to show just how different he is from most cornerbacks on this level of football, even as a redshirt freshman whose conditioning was hurt by a year of injury.
There were also quite a few teams who list all safeties and cornerbacks as "DBs"; indeed the cornerback sample we did get seems like it wouldn't change much. If you care here's Michigan's expected 2015 backfield rotation against the distribution of one year's Power 5 cornerbacks.
Interesting side-note: Florida's cornerbacks last year under Durkin were the smallest of any school in the Power 5. Using the formula from the chart above, Auburn and Minnesota were by far the biggest defensive backfields—both teams were about 6'0/200 with their cornerbacks. I know Minnesota at least is a man-all-day-long team. Nebraska and Ohio State were top five biggest, Iowa and Notre Dame around there and Stanford relatively big. Michigan was smallish—right around FSU and LSU. TCU was the second-smallest at CB.
Anyway Countess isn't the little guy according to the rosters; Lewis is. Jourdan's game is based on his recovery speed. He is just okay at jamming a guy at the line, but is so fast on a dead run and so quick to change direction that he doesn't have to stonewall his guy.
