The battle for the Bucs' last one or two receiver jobs remains a wide-open competition, but one name drawing consistent praise is second-year receiver Jesus "Bobo" Wilson."Bobo's having one of the best offseasons of anybody," coach Dirk Koetter said after Thursday's OTA practice. "I said at the end of last year he was one of the most improved players. Two guys, receiver-wise, that stick out almost every day are Bobo Wilson and Freddie Martino. … Bobo has gone from a guy that could only play one position to a guy that could play all three, which helps his chances. He's just become so much more coachable. Part of that is knowing what you're doing, it makes it easier to play fast, and he has no problem playing fast."Wilson spent most of his rookie year on the Bucs' practice squad, but was called up for the final three years, getting a single catch for 18 yards and a touchdown against Carolina. The former Florida State star will have a chance to win a return job as well, but his old college quarterback likes what he's developing into as a receiver."Just grit. I call him 'Young Antonio Brown' because of just his work ethic," quarterback Jameis Winston said. "He's constantly working, he's constantly processing and growing. I'm blessed to have him here with me because we had a good connection at Florida State so just to see him out there doing his thing, I'm very proud of him. But as we all know, this is the NFL so everyone has to compete. Everyone has to get better. He definitely takes on that challenge because he's going to compete with the best."The Bucs' top four receiver jobs are safe bets for Mike Evans, DeSean Jackson, Chris Godwin and Adam Humphries, but the fifth spot (and sixth if they opt for one) are widely up for grabs. Fifth-round pick Justin Watson would be seen as having an inside track, with Martino and Bernard Reedy bringing experience and special-teams value to the competition.
