The Jets have 11 or 12 OLmen currently on the roster. 8 will lmake the 53, probably the same 8 as last year. They will carry at least one on the PS.
The Jets do not have a good track record of drafting OL after round 3.
As far as tight ends. No tight end in the league or college is big enough to transition to play RT down the road. A smaller college tackle (270) "might" be able to play TE not the opposite as a general rule.
