If I remember correctly, Hartline wasn't a teammate - just a (jealous?) ass.
During his time in Oakland, he got along fine and worked tirelessly to improve his game.
He's a hard worker who has seen some success as a result of his stick-to-it-iveness. That could rub some lesser-achievers the wrong way, I suppose.
At any rate, it kind of sucks that he jumped into the D.C. volcano - wish that he would've landed with a team where he could really flourish.
Hartline spent an offseason, training camp and I think one or two games on the roster with Pryor.
However...he was also a teammate of Pryor's at Ohio State.
Pryor is a project still, and a rather old one at that. Decent contract to see what he's got, but as an Eagles fan I'm glad they didn't sign him.
He should be due for some major targets though, so fantasy wise I'd take a shot on him if the price is right
