ESPN.com's John Clayton offers his thoughts from the combine. Here are the five things that stood out for him: Running backs, thanks to underclassmen, exceeded expectations; very little sorted itself out at quarterback; this draft will be loaded with great defensive athletes; size and speed highlight the wide receiver position; offensive tackle may be the strongest position, but we learned the least about them.

SI.com's Don Banks says Illinois running back Rashard Mendenhall opened some eyes during the combine. Banks also says that speed-rushing defensive ends are in high demand because of the Giants' Super Bowl win. He says Ohio State defensive end Vernon Gholston helped himself in Indy:

Gholston, another potential outside linebacker in the 3-4, probably helped himself at the combine as much as any other defensive lineman. The junior ran a 4.67 40, did a whopping 37 reps, and had an impressive workout Monday that seemed to cement his top 10 status. Gholston had a three-sack game against Michigan last season, and one of them came against the Wolverines' standout offensive tackle Jake Long, a near-certain top five pick who only gave up two sacks his entire career in Ann Arbor.

Here's my draft profile of Gholston in case you missed it.

SI.com's Banks says no player has fallen further fast than Kentucky quarterback Andre Woodson. Banks adds that Delaware quarterback Joe Flacco could overtake Louisville's Brian Brohm as the second-ranked quarterback behind BC's Matt Ryan.

SI.com's Peter King says while there are questions surrounding Ryan, he's probably a better prospect than last year's No. 1 pick JaMarcus Russell.

Alex Marvez of FoxSports.com explains that escalating rookie salaries make picking No. 1 even more difficult.
