1) Slow with Sam.Sam Bradford's comeback from his second ACL surgery in as many years will be a major story come July, and the expectation is that he'll be into the third and final phase of his rehab -- "prepare to play," as Chip Kelly calls it -- at the start of camp. Caution will remain important, though. As one prominent orthopedic surgeon explained it, an ACL tear is 15 times more likely in a football player's first year back (that already bit Bradford last August), and a second consecutive tear not only increases that risk but also necessitates more time for the graft to solidify and usually involves more swelling (the Eagles shut down Bradford for a week at one point in the spring). The bottom line here is the team probably won't have a handle for a while on where Bradford will be at in September, which makes the longer-term future a little murky as Bradford enters the final year of his rookie deal. To that end, sources on both sides of the table have indicated several attempts to spark contract talks have failed, which makes sense since a) there's uncertainty about the knee and b) Bradford doesn't need to do any negotiating to get his $12.985 million for 2015. It is worth reiterating, though, that the Eagles do get a 2016 third-round pick back for Bradford if he doesn't play this year, and a fourth-rounder if he plays less than half the season.
