Risk or Reward?Keenan Allen (California) Suffered the injury on October 27th against Utah Allen hurt his knee on a failed onside kick attempt by Cal with 1:18 left in the game. Ended up missing three games due Grade 2 posterior cruciate ligament tear in his left knee The 6-3, 212 pound Allen was projected to be a possession-type receiver by NFL draft Analysts after amassing 205 passes in three seasons for the Golden Bears. Projected by some to be a first round pick based on his size, catching ability, route running and punt returning. Did not participate in the NFL combine like he originally hoped Finally works out for scouts in early April and Mike Mayock of NFL network times him in the 4.7 range, slow by wideout standards - did the PCL have anything to do with that or are his quad muscles just possibly weaker since the injury? Allen himself says he's "85 percent" recovered from the injury Talk about PCL's structure and function, possibly compare it with the ACL How to diagnose PCL tears - MRI or physical exam maneuvers? Difference between grade 1, grade 2, grade 3 PCL tears Why was this injury not treated surgically?

Star Lotulelei (Utah)Reported in February that he would not be participating at the combine due to a low Ejection FractionEchocardiography shows that Star's heart is only pumping at EF of 44 percent while normal is 55- 70 percentDeemed a top-3 pick in many mock drafts before the combineEcho was repeated at Utah shortly after the combine, and the efficiency had reportedly improved - speculation that a viral infection might have caused a temporary drop in his ejection fractionAnother source (USA TODAY) says the heart condition might have been caused by dehydration, too much sodium in his diet, or rapid weight lossRecent testing (April 1st) reveals he has "no evidence of dysfunction," and that medical exams found his heart function performed "consistently with that of highly trained athletes," according to Dave Petron, Utahs team physician. Remark on how screening is a necessary portion of the evaluation process - especially in a case like Lotulelei where his condition might never have surfaced since he never exhibited any symptoms
