His lack of bulk (6', 180) and underwhelming 40 time (4.53) lead to Steve Breaston falling into the second day in this year's draft. While he may not be able to start (especially on a squad as loaded at wide receiver as the Cardinals), he definitely will play a role in the team's success this season.
Exceptional hands and good technique.
Fluid in his routes and very dangerous in space with the ball in his hands, stemming from his extensive return experience.
Amassed over 1,500 yards receiving, 1,500 yards on punt returns, and 1,500 yards on kick returns during his four year career at Michigan. So, he has college production at a big time school.
Explosive on returns, both on kickoffs and punts. Always seemed to come up with a big play at a crucial time during his college career.
Michigan does not exactly have a strong track record of producing NFL-level talent at the receiver position. The list of failed prospects from that school is long and filled with failed experiments. The jury is still out on Braylon Edwards, though.
Too light to play at this level and needs to bulk up, especially if he is going to see any significant playing time in the kicking game. Could be an injury risk.
Struggles getting off the line, particularly against the size and caliber of players that he is likely to face in the NFL.
Doesn't project to be much more than a slot receiver and return specialist, due to his size and speed constraints.
All Arizona needs at this point is a decent slot receiver and a solid return man, which is exactly what Breaston seems to be. The Michigan hex and the fact that he's undersized but not all that fast dropped him to the fifth round (and most likely further had the Cardinals not taken him - ranked as the 272nd best player by Scout out of a possible 255 draft selections).
In the fifth round, Arizona could have done far worse than to take a guy that has proven return skills and could see some spot duty as a slot receiver when they go with four wide-outs. For a fourth or fifth receiver on a team that is three-deep at the position, he fits in rather well.
There seems to be an emphasis in the new regime on doing all the "little things" better. Breaston dovetails with that very nicely.
