It depends. Right now you have Big Boot at 12, I'm guessing from AE, so would you have to lose some BB in order to upgrade this piece? Your Punting is also at 114 with all your gear in it, so I'm not so sure how much better you'll get by bringing it up to 117. You have 4 career tackles. so a make tackle boost is just a nice to have.
The only reason I can think of for buying it is that next season your player starts to decline so it might be worthwhile to sacrifice some BB to improve a core stat.
