Prospects to watch at combine: | | | | | The is Feb. 17-23 in Indianapolis, and it brings together 323 othe nation's most draftable players and numbers front-office representatives and scouts from each NFL team. A big portion of the combine is the individual events, such as the 40-yard dash, the bench pre s and the vertical jump. This is part four of our position-by-position look at the combine, spotlighting offensive linemen. We look at six prospects who will be scrutinized this year and also look at noteworthy event performances in the past five combines. We'll also look at how notable current NFL players performed in their combine events. Six to watch this year OT , Pittsburgh: Clemmings has played just two seasons on the offensive line after moving over from the defensive line. And those two seasons were at right tackle. He would seem to have the nece sary attributes to play left tackle -- "He has the physical traits to become a left tackle," NFL Media analyst Lance Zierlein says -- but struggled a bit at the . He has some work to do to prove he can play of the left side -- i.e., the side that will make him the most money. He can help himself by showing off his athleticism at the combine. OT , LSU: At one point, he was considered to be in the mix to be the first tackle taken, but he has fallen down most draft boards and there is a concern he cannot play left tackle at the next level. Zierlein says Collins "lacks (the) athleticism to be a consistent left tackle and will have to move to right tackle or bump inside to guard." And fellow analyst Daniel Jeremiah has Collins as the and the No. 4 tackle. A strong combine performance in the 40 and in the drills might start to change some minds. OT , Miami: Jeremiah has Flowers -- who left school after his junior season -- as the No. 33 overall prospect and the No. 5 tackle. He is considered to be further along as a run blocker than as a pa s protector. Flowers is a better athlete than a lot of folks think, though, and might be able to open some eyes with his combine performance. He was a high school and college teammate of RB Duke Johnson, , he could make a move at the combine into the top three or four of his position group. OT , Stanford: Peat is a big, physical run blocker, but there are concerns from some about his pa s-protection abilities. He did not play all that well against Utah, which had four sacks against Stanford. As with Flowers, Peat left school after his junior season. It will be interesting to compare his combine numbers with those of the other top linemen. Despite the concerns, Peat -- whose dad, Todd, was a guard in the NFL for six years -- could be the first tackle off the board. OT , Colorado State: Sambrailo is the best offensive lineman from outside the Power Five conferences. Zierlein notes that he looks to be a mid-round guy, "but if in the bench pre s, it's going to really hurt him." Sambrailo's work in the drills will be closely monitored; he seems to have the needed athleticism to play left tackle at the next level. Former Colorado State offensive line mate went in the second round of the 2014 draft, to the , and was a rookie starter at guard though he played mostly center at CSU. OT , Penn State: Smith left Penn State a year early, but was a participant because he already has graduated. While he was criticized for his early-entry decision, his work at the was better than expected, and he Devonte Young Jersey will be a closely monitored lineman at the combine. He is a big man (6-5, 335) who might fit best inside at the next level. He will be looking to show that he has the needed athleticism to play tackle; the perceived lack of athleticism is a knock on him. Combine best over past five seasons 40-YARD DASH 1.
