PHILADELPHIA — Quarterbacks, quarterbacks, quarterbacks.

The Eagles and their signal callers have remained the topic of discussion down at the NovaCare Complex, and Monday was no different, as a large media contingency watched practice under the blazing sun.

Here are 10 observations from Monday's practice, starting with of course, the quarterbacks.

1. Tim Tebow: Tebow might have the slowest release out of the four quarterbacks on the roster, something that is becoming clearer every time he throws the football. That doesn't, however, mean he hasn't been effective. Tebow, just like the other quarterbacks, had some good and bad throws on Monday.

His best throw of the day was towards the end of practice, when he hit rookie Nelson Agholor in the corner of the end zone for a touchdown from about 20 yards out. The ball had nice touch on it and his Agholor where only he could get it. His worst throw of the day was in seven-on-seven drills, sending one right into the ground when trying to hit a receiver out in the flat.

2. Sam Bradford Bradford took another step forward on Monday, taking part in warmups with the team. The past few practices he has been on the sideline with trainers. Every step Bradford takes in the right direction is noteworthy as he tries to recover from his second torn ACL in two years.

Bradford once again took part in seven-on-seven drills, and looked like the best quarterback out there. His best throw was one down the middle of the field to tight end Zach Ertz for a long touchdown.

3. Quarterbacks: At the beginning of each practice the Eagles have their quarterbacks throw a baseball into a net, a drill that Tebow did over the past two years to work on his throwing motion. Offensive coordinator Pat Shurmur mentioned last week that the team has incorporated some of Tebow's drills that helped him fix his throwing motion, and the baseball drill is one of them.

4. Music: During every practice there is one song that gets the players on the team going, and on Monday, it was "Can't tell me nothing" by Kanye West. A title that also fits the power that head coach Chip Kelly has in the building.

5. Taylor Hart Second-year player Taylor Hart is facing a big offseason, as he was inactive for every game last year after being selected in the fifth round. Hart very well might impress once preseason games begin, but to the naked eye, he doesn't look much different than he did last season.

6. Marcus Smith: Smith is still recovering from a muscle injury he suffered late last month, and spent the majority of practice on Monday with trainers. Smith did get onto the field for some individual drills, but didn't take part in anything with the team. The longer Smith is on the sideline, the less and less secure his roster spot becomes.

7. Brett Brown: The Eagles had a special guest on Monday, as Sixers head coach Brett Brown was in attendance to watch practice. Brown and Kelly are close from their days in New Hampshire, and Brown has said in past interviews that the two talk frequently now that they both coach in Philadelphia. No word on if Kelly told Brown to talk Marcus Mariota with the Sixers' No. 3 overall pick in the 2015 NBA Draft.

8. Special teams: With the rest of the team doing team drills, long snapper Jon Dorenbos, kicker Cody Parkey and punter Donnie Jones were working as well — but not on football. With Parkey pitching, Dornebos tried to hit the football with his helmet, knocking one of them about 10 yards. Welcome to life as a kicker or a punter.

9. Mychal Kendricks Despite the fact his name was involved in plenty of trade speculation this offseason, it looks like Kendricks has held onto his starting spot among the inside linebackers. Kendricks is always with the first team during team drills, and even during individuals, Kendricks is the first one up. Of course, the fact that Kiko Alonso is new to the defense and DeMeco Ryans is still recovering from an Achillies injury might have something to do with it.

10. Nelson Agholor: Not a practice goes by without Agholor making a catch that catches your attention, and Monday was no different. As mentioned above, Agholor hauled in a nice catch from Tebow in the corner of the end zone, going up and over the cornerback to bring it in.
