Fleener and Allen are poised to become the NFL's most dangerous 1-2 combination at tight end. Each has the ability to work the vertical portion of the field while also doing the dirty work between the hashes. Fleener in particular has grown into his role as the "move-the-chains" guy in Indy, having produced first downs on 61.5 percent of his receptions in 2013. Although Fleener, who did most of his damage down the middle, is at his best playing as a "slot" receiver, he can also play as a traditional tight end, which creates problems for defenders when the Colts trot their "12" personnel (one back, two tight ends and two receivers) package onto the field.
