Unsolicited advice for QB Jones, DE Lewis

Big 12 blogger David Ubben gave advice today to the conference's underclassmen who could turn pro after the season. Here's what he said about two Oklahoma stars:

Landry Jones, QB, Oklahoma: Jones struggled at times without Ryan Broyles, and his numbers clearly regressed from 2010 to 2011. The physical skills are there for Jones, but he still has a lot of room for growth. And though Broyles will be gone in 2011, he'll have solid targets next year in Kenny Stills and Jaz Reynolds, and a team that brings back a lot offensively. His stock is dropping, and his fiancé still has another year left at Oklahoma. What's the rush?

What he should do: Stay at Oklahoma for his senior year

Ronnell Lewis, DE, Oklahoma: Lewis could still grow as an athlete, but you never know what could happen between now and next season. He nearly failed to qualify academically before the season, and after injuring his knee, was suspended for Bedlam for missing class. His stock has dropped a bit, but could jump back up when NFL scouts see his raw athleticism at the combine.

What he should do: Enter the NFL draft

What do you think? Should Jones and Lewis return to Oklahoma in 2012 or enter the NFL draft?
