Although he's still in a walking boot, Patriots TE Rob Gronkowski confirms that he's "on pace" in his rehab from February ankle surgery.  "...I'm just getting better day by day and week by week," Gronk said.  "I feel way better than last week. I'm just walking around now, taking it easy, and hopefully I'm 100 percent when it comes down to that time so I can get to where I want to be this offseason."  Gronk remains iffy for OTAs but should be completely recovered in plenty of time for training camp.
