Ten quick impressions after watching the University of Wisconsin football team's first scrimmage of spring practice:
1) Converted defensive tackle Kyle Costigan is an intriguing player at right guard. He can move and he's aggressive.
2) The right side of the offensive line is in a state of flux and the lack of depth on the line overall is mildly alarming.
3) With Jared Abbrederis sitting out, none of the wide receivers was getting much separation on routes. UW will need someone to stretch the field.
4) Tailbacks James White and Melvin Gordon looked quick and strong. They are performing well enough to push Heisman candidate Montee Ball, which is saying a lot.
5) Quarterback Joey Brennan looks the part but just isn't a consistent passer yet. Despite making an occasional nice throw, he lets too many balls get away from him.
6) Converted end Warren Herring looks like solid addition to an already strong group of defensive tackles. He's got some explosiveness.
7) The coaches must find a playmaker or two among the inexperienced defensive ends behind solid starters Brendan Kelly and Pat Muldoon. I'm talking about oft-injured juniors David Gilbert and Tyler Dippel, sophomore Konrad Zagzebski and freshmen James Adeyanju and Jesse Hayes. Adeyanju has excellent speed.
8) Middle linebacker Derek Watt, J.J.'s little brother, has bona fide playmaking ability. He had four tackles behind the line of scrimmage and an interception in 7-on-7 drills.
9) The surprise of the spring? Outside linebacker A.J. Fenton. He can really run.
10) The secondary has the best across-the-board size it has had in forever. When cornerback Devin Smith is cleared for 11-on-11 work, probably next week, the shortest of the top five defensive backs will stand 5-foot-11.
