Not surprisingly, areas of need -- tight end, wide receiver, and safety -- received extra attention from the Buffalo Bills with their 13 signings of undrafted free agents Friday.
That is consistent with the way they proceeded through free agency and the NFL Draft.
The list of undrafted acquisitions includes two tight ends (Jason Croom of Tennessee and Keith Towbridge of Louisville), two wide receivers (Brandon Reilly of Nebraska and Daikiel Shorts of West Virginia), and two safeties (B.T. Sanders of Nicholls State and Jeremy Tyler of West Virginia).
In addition, the Bills added former University at Buffalo running back Jordan Johnson, South Carolina defensive end Marquavius Lewis, Virginia Tech defensive tackle Nigel Williams, Idaho punter Austin Rehkow, and guards Greg Pyke of Georgia and Zach Voytek of New Haven.
The most notables pickups appear to be the tight ends.
The 6-foot-4, 246-pound Croom, who has a chance to be noticed at a spot where the Bills' depth is sorely lacking. He was projected as a seventh-round pick, so the fact he went undrafted wasn't exactly a shock.
Croom's tendency to drop passes (he had seven drops to 60 career receptions), poor pass protection, and missing two seasons (2012 and 2015 with injuries) were viewed as the biggest reasons he went undrafted.
However, NFL scouts liked his speed and athleticism. He does a nice job of running routes and is a solid run-blocker.
Towbridge's size (6-5, 262 pounds) was enough to draw the Bills' interest. He blocks well at the point of attack, and although he needs work with his overall blocking technique, his frame allows for significant improvement in that area if he has the time to develop. Towbridge also is surprisingly fast for his size, but wasn't very productive as a receiver with only 21 career receptions.
His size, alone, could at least earn him a spot on the practice squad.
