No, not ready yet, won't be drafted until later rounds if so at all IMO. Needs a strong, solid senior season to improve his stock IMO.
That being said, he's having both a very good season and career to this point, despite playing in an historically bad Tennessee pass offense for most if not all of his career.
If he stays on his current pace and he plays in 4 more games this year, he'll finish with 49 catches for 866 yards and 11 tds in 2016. Not bad considering our less than average pass offense and his wildly inaccurate quarterback.
Also, if he stays his senior and has an identical season next year as this year, he finishes his career at Tennessee with 152 catches, 2,372 yards and 25 td catches.
By my count that makes him 4th all-time in catches, 3rd all-time in receiving yards and tied for #1 in touchdown receptions. Not bad for a kid who's gotten so much criticism and disrespect from so many fans over the last 3 years.
