The first has to do with his character. Floyd had numerous alcohol-related incidents during his collegiate career, including a DUI before the start of his senior season. He spoke about learning from his mistakes but it's truly anyone's guess whether he's mature enough to handle being a millionaire pro.
The second had to do with his speed. Floyd is a big-bodied wideout – measuring 6-3, 220 in Indianapolis – yet it was unclear whether he had enough speed to create separation at the next level.
WR Michael Floyd
Floyd clocked in at 4.47 in his 40-yard dash on Sunday, effectively erasing any doubts about his ability to run. Most assumed he would run in the 4.50-4.60 range, yet no one predicted a 4.47 pace.
It's clear now that Floyd – who runs good routes, has great hands and can get after the jump ball – has the speed to be a deep threat in the NFL. Many had Floyd penciled in as the first-round pick for the Chicago Bears at 19 overall. Yet after the show he put on at the combine, it's unlikely he'll drop that far. There will surely be a team ahead of the Bears willing to overlook his off-the-field issues. At this point, it will be a miracle if he drops far enough for Chicago to take him.
Another wide receiver option for the Bears is Baylor's Kendall Wright. Many assumed he would post a blistering 40 time, after demonstrating blazing quickness on the field during his collegiate career. Yet Wright clocked in at 4.61, an amazingly slow time for a player that appeared to have breakaway speed. He may have run himself out of the first round with his performance in Indianapolis.
South Carolina's Alshon Jeffery did well for himself this weekend. Pre-combine concerns with Jeffery were his weight and speed. He measured 6-3, 216 pounds – far less than the reported 230 at which he played during his senior season – and ran a 4.45 40. With his svelte frame and good speed, he just become a much more realistic option for the Bears in the first round.
One player that truly turned heads was Georgia Tech's Stephen Hill. The 6-4, 215-pounder ran a 4.36 40, the fastest time of all the wideouts. He was considered a second round option before the weekend but may have propelled himself into the first round. The Bears need to take a long, hard look at Hill over the next month. This kid could be special.
Another player to watch is Miami's Tommy Streeter. He measured 6-5, 219 and ran a 4.40. Considered a third round pick right now, Streeter easily propelled himself into the discussion of second rounders. If the Bears choose not to draft a receiver in the first, Streeter would be a very intriguing option in the second.
Other receivers who helped themselves: California's Marvin Jones, 6-2, 199, 4.46; Ohio State's DeVier Posey, 6-2, 211, 4.50; North Carolina's Dwight Jones, 6-3, 230, 4.55; Wisconsin's Nick Toon, 6-2, 215, 4.54; Iowa's Marvin McNutt, 6-3, 216, 4.54; Texas A&M's Jeff Fuller, 6-4, 223, 4.52; Illinois' A.J. Jenkins, 6-0, 190, 4.39.
